I took the bike out this morning for the first time since installing the Deuce risers. All I can say is- if you're 5 foot 10 or so and still experience shoulder burn with either the Lamont or Aeromach risers I recommend the Deuces. Grips are right where they'd be if I closed my eyes and put my hands where they were most comfortable. Slow speed maneuvers are easier, too. I had shoulder surgery last year and have since had trouble extending my right arm fully and these risers really help. All that's left is to install my recently-ordered extended throttle cables.
(By the way, if anyone's looking for a pair of Lamont risers in fair condition, let me know. I bought them 2nd hand and had them on my bike for 5 years. The chrome is decent, but less than perfect)
