I have just recently started going to roll sessions in a local pool but have had a hard time finding boats that are even halfway comfortable. I am 6'2", 190lbs, with size 13 feet. I consider myself somewhat of an average sized guy and assume that there are lots of kayaks out there that I can get into. I just don't know what to look for. I am a beginner so I don't really even know what type of boat I want. I am interested in river running on whitewater and possibly just kind of playing around on the surf. So far I have gotten into a Perception Overflow (It hurt my feet) and a dagger RPM (this wasn't bad) If anyone can give me any suggestions or any ideas of where to pick up a used kayak, I would greatly appreciate it. Thanks.
