I sit a couple of inches higher and am a bit wider then yours from what I could determine from the spec's........very jealous of the telescoping boom.......wonder what the pt pucker factor will be with that.......got to tell you when you're sitting up high and that happens you get religion real quick......lol.........have fun with it......Jack
So far the sitting up a bit higher appears not to be a problem at all. Maybe on a very steep incline it might be an issue but really have not noticed. The ability to see around in the back of you is also very nice.
