100% satisfied. The G2 Ergo tube and cam is a great product, great quality, excellent design (I own several). But I've specifically modified the OEM throttle tubes for people using heated grips with great success. A Dremel tool and a couple hours of patience will get the job done nicely.
Hint... Use a flat-edged needle file to re-create the cable groove down the curvature of the new cam shape. You will notice that the one cable tends to stay "jacked away from" the seated position and needs a little bit of extra groove to make it rest flat and comfortably against the cam surface.
