At your size the Diesel 65 would be a dream for what you said you want it for. I'm 150 #'s and I use the 65 to get me down Mann's Creek, WV as well as the Upper Gauley at 18,000cfs. The boat just feels "right" if you know what I mean. The edges are extremely useful yet unobtrusive. Good speed for a 7.5' boat too. Let me know if you have any more ?'s.
