I am looking at a Dagger Mamba online and would like to purchase it. The only problem is that I am little hesitant as to what size to buy. I am 6'1\" and 150lbs, but have an inseam of about 33\". I want to be able to use the kayak for a long time but don't want it to be too big by getting a larger model. Suggestions for either the 7.5 or 8.0 would be welcome!
