Dang, I always forget about that guy. I didn't know he had a website, though, I thought he was strictly eBay.
I haven't tried swapping the Comp & Super handles in quite a while, but IIRC there was something funky about the actuator on the Comp that caused the e-clips not to line up, or something like that. I do know that the Comp & Super have different length shafts, but there was something about the e-clips... Maybe it just needed a different sized spacer... Hmmm, if I get a few momemnts this evening, I'll check that out again because now I'm curious.
