Hi, I currently sail a freewave STB 2018 85L. I mainly sail bump and jump conditions, forwards and trying to learn back loops. I mainly use 4.4, 4.0 and 3.7 Severn S1's. I weight a mere 58 kilos. I find the STB can be hard on the knees in the short chop conditions we get, so my question is it worth going down to a 75L 2020, newer shape freewave
Thanks
