I am 6'1" 275 and had done recreational kayaks and taken several classes before buying an Eddyline's Denali. I did my research on which kayak to buy, I focused on weight capacity, cockpit width and price settling on Eddyline's Denali.
I found the Denali extremely unstable initially and after adding a ballast system (Paddling Partner) I never felt really confotable with the secondary stability after two miles, or so of paddling. This boat may be fine for someone with a lot of experience but I was VERY happy for REI's 100% satisfaction guarantee policy.
