Just wait till you get the gripper, it's much tackier than the stocker! While riding with the thor/msr pants on it used to twist my knees since my ass slid around, but now I stay where I sit.
AND WHAT A WHORE TO GET IT ON. Man, that sucks. I have to finish it up tommorrow when i go buy a diffrent staple gun, the one im usuing just dosn't want to work.
Yeah, it's a pain but well worth it. You just have to push on it reaaaaalllllly hard. You also have to remove staples and pull it tighter as you go quite a bit.
