I have mainly used my RAD in the surf both in Dunedin and around the Southland Coast. I would have to say it peforms pretty dam well in the surf and I havent felt restricted by ther boat in any way. The Volume is a little bit above my weight but due to my height its what I had to get, and I have not had a single problem with it cartwheels, loops all the flatwater stuff is fine with a bit of practice lol. In the surf it is simple to get massive air and do anything you want, Bliss-Stick didnt call it Radical Aerial Device for no reason. Ive taken it down some big water rapids and it handled just fine, you just have tro keep that weight foward! lol
In conclusion it is a great boat.. I love it..and would reccommend it to anyone whos looking to go a wee bit bigger..
