What riser are you running currently? 8" is WAY to much for a 6'1" guy on a IQ RMK. I'm 2" taller and use the factory 5-1/4" riser. You could go to a 6" riser without much work, but any taller and you will need to relocate/extend cables. When you get to tall of a riser, you actually loose the ability to control your sled, especially on a sidehill.
