I found a reference to Powerball on this thread and ended up buying one. Amazing. It rehabbed my shoulders and those of a friend within minutes!
Years of action sports and a brain dead e-scooterist have left me with shoulders a bit worse for wear. A few minutes with this and I had shoulder range of motion that I haven't had in ages. My friend has been suffering for 3 months from something like RSI. It was 95% gone within minutes.
I got it for about $130 on Amazon Australia.

My fingers got super achy and sore when I was using my f-one swings. Almost like early onset arthritis, where it hurt to open and close my hands. I modified the handles and it helped, then switched wings and the pain is gone.

Midatlantic, what was the modification you did? Also what wing did you switch to that resolved the issue? I especially feel that when getting up in the morning after previous day heavy sessions.

This mod has been working well. My aching fingers improved significantly.

So that thing actually works ? Honestly watched the vid and thought it's one of those ridiculous scams . spinning a metal ball in your hand . well I will be damned. Cool.

Midatlantic, what was the modification you did? Also what wing did you switch to that resolved the issue? I especially feel that when getting up in the morning after previous day heavy sessions.

Also keen to know what you did to modify. I'm a doctor and I just about diagnosed myself with early onset arthritis as the sign and symptoms matched perfectly when I started winging regularly. But as they say, common things occur commonly and now I ascribe the stiffness to winging. Have experienced it across brands with handles (I've never used a boom) so it's probably my technique and not the brand. I can live with it, but it's very noticeable in the mornings (and morning stiffness of small joints is a classic sign of arthritis). As the joints warm up the stiffness improves. I thought it would improve over time, but I still get it after a big day.

First i tried cutting a section of small diameter pvc pipe lengthwise to put inside the handle (duct taped in place) so my fingers would have a curved, laterally flat surface to grip (as opposed to a more squared off U shaped handle). That was somewhat harsh (no padding), so I think I ended up adding a layer of pipe insulation with duct tape. This kinda sucked, which added to my motivation to get a quiver of new wings.


I think what caused the issue for me was a combination of the radial bend of the handles and the square edges. I naturally have 'bony' knuckles, and it just seemed to be a bad combo. Torsional, unergonomic stress coupled with hard edges did my hands in for a stint.


My new wings are BRM (boardriding Maui), which are hard to get outside the USA. The handles are amazing. The front handle has a cant to it so that your wrist and hand are in alignment when trucking upwind under tension. Handles are rigid and straight, no U shape crap, with a rounded grip side and flat underside. I think the new Cabrina Mantis have similar structure to their handles.
Also, I have 4 sizes of wings so I can pick the eyes out of the wind and get my preferred power level. Before I was only on a 5M or 3.5M. I'm now using a 2M more than I ever expected.

Another finger related injury I had was some kind of deep tissue damage between my index finger and middle finger. Hurt it while flagging the 5m Swing and using my index finger to guide/stabilize the wing while wave riding. Or it may have been while gybing with hand on front strut handle and finger extended) (can't remember) The Swing swung and it felt like there was a lateral separation in between that joint. Super painful and kept injuring it repeatedly while it was healing just opening my hand. Finally made a splint and weeks later it healed. So be careful about finger guiding the wing. Newer gear with stiffer handles are lowering the likelihood of this type of injury.

MidAtlanticFoil - thanks for the details. I had tried a previous iteration of the Cabrinha Crosswing. I liked the feel and handling of the wing but did notice some fatigue in the forearm due to the large dia but had not considered the ergonomics. Since BRM is not available outside of the US I will look at other wings such as the Cabrina Mantis/Crosswing.

Could you tell me what dia of the BRM handles is.

82mm diameter. Smaller than the cabrina I believe.
Here's a photo of the back strut handle. Wing is deflated.. the strut material isn't rubbing fingers when inflated.

Midatlantic. - Your diameter seems a bit off. The Armie bar is 24.0 mm( so just over an inch)

Anyone else - have a measurement for the Cabrina Cross wing and Mantis. Any other wings with tube handles?

Edit: the BRM's circumference is 82Mm

Add my vote for hand/wrist/finger injuries from either crashing with the hand in the handle, or getting flung and landing on the leading edge.

I use straps and have a "go down with the ship" approach to them. Specifically, I find if you're going to use them, you need to commit and make sure your feet are locked in for wave riding and jumps. The last thing you want to have happen is have one foot stay in and one come out (unless you are for some reason doing that intentionally). I lived through that on an aerial years ago windsurfing and it was bad. I was off the water for a year.

When you keep the board on your feet in a crash, I find you are much more capable of maintaining a board position where you will not land on the foil or twist an ankle or leg.

Nobody mentioned a broken wallet and cracked credit card limit yet?

Nor having to ask for forgiveness rather than permission by "she who must be obeyed". And possible back injuries by having to sleep on the couch.

Elbow injury after wing session last night. Pretty painful to move. Bloody typical, just before summer holidays!

I seem to be having a bad run of injuries recently but mostly associated with either gnarly conditions or learning to tack. Windsurfed for nearly 40 years and have had more injuries in 15mths of winging! My list of injuries which mostly have been sustained in the last 4 mths as I tackle more challenging conditions / moves :

- shoulder bursitis soreness (7 days off)
- Cut under eye (4 days off)
- Cut back of the head (medically treated , 7 days off)
- bruised ribs (10 days off)
- various ankle sprains (no time off)
- elbow hyper extensions (no time off)

Hey Stretch. Have you crossed over to the dark art. It's highly addictive. I smacked my elbow last night but ice, nurofen and 10knts seems to have done the trick.

Let's call it dabbling Tim! I'd like to get proficient at it, but so far I'd have to say windfoiling is easier to learn and not as hard on the body (except for hooked in crashes, they hurt

My fingers got super achy and sore when I was using my f-one swings. Almost like early onset arthritis, where it hurt to open and close my hands. I modified the handles and it helped, then switched wings and the pain is gone.

Intersting, I sold my slicks because I felt that I was hurting my wrists and circulation with the boom and went to ozone and F1. Hands are still a bit stiff but my wrists feel better. Harness is a help if holding long tacks.

My credit card is very injured.
