Comparison of EZ to Fun series thigh braces
I switched from a Super EZ to a Super Fun this year. I initially had the same concern about the thigh braces. What I've found is with the Super Fun there is more knee to thigh contact and the fit functionality is superior without the added weight.
It is important that you understand how to adjust the outfitting in the Fun series boats, but when you do, you will find that you can get a dialed in fit with the stock outfitting. Good luck with your choice.
