Honestly, at 6'4" 265, very noticeable ridge in my WBBB 1.7 dbl, but easily dealt with with a level pitch (not a fan of the "feet high" theory) and a knee pillow. Like "super-comfortable" dealt with. I recently put an ARL in and that seems to have helped as well.
Now my TTTG SB 1.9 single = very, very minimal. Almost none. I have a PapaSmurf Dangerbird that should be here this week, I'm anxious to compare out the three.
