Hey all, just wanted to know if anyone gets a sore lower back and sore top of knee caps during and after kiting?

Got into kiting at the end of '08 and been hitting hard in the WA summer going pretty much everyday. Just noticed lately though that my lower back gets pretty painful after only being out for 30mins or so. I use a DaKine Tabu waist harness and havent experimented with a seat harness yet, but maybe this is the way to go?

Any suggestions out there? Cheers!

Hey,
am into the surf, old school, jumps and all, due to my age!!!! Looking for a new board. Am using Liquid Farce 134 cm with North kites. My buddies say that my board is too stiff but I would like some impartial advice on what size/ brand to go with for a light wind wave/ jump board..
