I know this must be old news, but, I'm a WW paddler wanting to do some lake paddling. I'm 5'10" 175 lbs. size 10 shoe. Will I be cramped in the 165 or wallowing around in the 170? I like a tight fit, as far as being locked into my thigh braces in my Diesel and Blaze, but I don't find myself catching eddies or carving and surfing on the lake. thanks for a reply.
