I'm using Rocky's Risers.
I'm 220, 5-10 and also had discomfort with stock setup.
Ergonomically, I found that with Rocky's, after adjustments I have almost a 90 degree elbow angle which I find very comfortable on long rides. I did notice however that when riding "the Dragon" I had the bars set a bit too close and too narrow. For pushing the bars in aggressive turns I would have liked to get them a bit wider and just a bit further forward.
I also have a rider's back rest so that will push me forward or back to hold the comfortable elbow angle as I get tired.
Now, this is the best part of Rocky's, They are adjustable... narrow to wide which also brings them forward or back. So since I do mostly longer rides and relatively few aggressive runs I'm unsure at this point if I will slightly adjust my bars. But it's nice to know I can.
