SpokeyDoke, couple of things I'd ask first.
What's your general skill level? If you're pretty well co-ordinated and good with windsurfing, you can consider going on the smallish side of a learners board (20-30L plus body weight in kg). If not, go bigger (I still use a Konrad 118L board and am 70 kg). The more recent designs are tending to go shorter, narrower but increased thickness to get the volume. My Naish 125 Hover is much more stable, but is not as easy to get flying as it's bigger surface area makes it stick to the water more.
What are your local conditions like? If water is choppy and gets a lot of exposure from a long fetch and wave activity, then consider going for a bigger volume board to assist with learning in compromised conditions. If it's smooth protected waters in a lake then a smaller board may give you more scope to learn with that board for longer.
I can vouch for Axis gear. Used it and the Naish plus Slingshot and all are good but I think Axis is a little better.
I've used the Naish 1572 and Naish Jetfoil 2000 to learn on. Was OK. Moved to Axis BSC 1060 and PNG 1300 and the learning took off. One of the things that may have contributed to faster learning was the Axis fuse I got was the windfoiling one (88cm long) which I found really stabilised the pitch, making gybing muuuuch easier. Yeah, it doesn't pump as easily as the shorter fuses and isn't as manouverable, but I can dial in a gybe easy in most conditions with it now.
What you want to do with your foiling will dictate your best choice for front foil. If it's just getting up and messing around in light winds (say sub 15 knots that you struggle get windsurf planing), then a big area front foil will be a good start. If you're looking to move into waves and speed, then a higher aspect wing might be more what you're after? It's a bit hard to know. The more info you give us on this topic, the more feedback you can get from a number of us that will hopefully steer you in the right direction.
For wings, I found it was about the wingspan. Anything bigger than about 3.2m wide and I have a tendency to touch the tips when trying to pump. So for me (at 175cm tall and with not great shoulders) I found the 5m Slick to be ideal. I posted a topic on this:
www.seabreeze.com.au/forums/Wing-Foiling/Wind-Wings/Windwing-dimensionsIf you have the opportunity, I'd recommend learning the foil aspect first behind a tinny at about 15km/h on smooth waters. I think there's topics on this forum which talk about learning to foil behind a boat.
When you first go out on the foil with the wing, give yourself a chance with about 15 knots or more. It's easier to dump power when winging. If you're underpowered it will likely be very difficult trying to learn how to pump onto the foil as well as everything else you'll be trying to control.
Good luck. If you get into it, I doubt you'll regret it. HUGE fun.
