Ya know, I was thinkin' here that Jason's short inseam and his 5'8" height COULD have contributed to this, because if one has to reach for the peg AND rear brake pedal, that it could make having a "light touch" upon said pedal kind'a tricky.
Jason, I think maybe you might wish to look into gettin' one of these set-back foot control units that Brent sells here....
