I have the MOP model GF and love them. I like that they mount to the vertical engine guard and don't scrape, and I like the outboard peg mounting. Right now I have Kury ISO pegs on them, but am always looking for an alternative. With boots on, my feet are huge and because of the boots, it's hard to "feel" where they are on the MOP pegs. I may just go to a standard round-type peg that will lodge in front of the boot heel where I can feel it.
Incidentally, when I wrecked a year ago and the bike slid down the freeway on it's right side, kicking out a shower of sparks, the MOP on that side was virtually unmarred. All I did was replace the cover cuz it had a small scratch in it. Had it been one of the models that mount to the horizontal guard, I probably would've had to replace the entire MOP on that side and my insurance didn't cover accessories at the time.
