Seriously...weight jackets are really the domain of experts only, for all the reasons Kato has stated.
If you are struggling in over 20 knots, you don't need a weight jacket, you just need practice!
Or just use heavier gear ?
What's the advantage with light weight speed/slalom rigs ?. I've got a 2010 Code Red 6.5 sail, and people are always complaining how heavy it is compared to their rigs. Yet, I can hold down this sail up to 30 knots and I'm an under powered sailor.
I can understand this light weight design concept with free ride and wave sails.
