Keep the Power Ratchets.
Funnily enough, though, I have what I think is an identical pair of your non-ratcheting shifters (I'm not looking at them right now so I can't say for sure they're the same, but they're close) that I'd been thinking about putting on the "ISO and For Trade" thread, in hopes of exchanging for a set of Power Ratchets. But I figured "nah, no one here would make that trade," and never bothered. Looks like I was right, too.
