I'm 190 and up there I ride a 13 Instinct Sport as my big kite most of the time.  On rare occasion I'll ride a 7M., but lots of days on the 9M (sweet at 30-35 mph) and also the 11 when it's in the mid 20's. You'll probably want a 5M as the small one and go from there  Maybe 5,9 12.  Whatdathink Jake?.  Have a great Gorge season.  Just starting to get going up there
