I've learned the hard way that you have to read the room before taking the time to put out a detailed explanation, but I'm glad some people still put in the effort. You've just gotta realize that, depending on your audience, you might get nuked by one stupid meme. At least SW has a decent cross-section between the peanut gallery and guys who really care about every nut and bolt; glad I don't bother with FB anymore - that was as bad as the courtroom scene from Idiocracy.
I haven't rode a boost yet, but generally if your priority is responsiveness, then gearing down can only help. Clutching is least efficient when it's nearest the engagement point, and by gearing down, you're able to get out of that zone more quickly, and will be closer to peak efficiency in low-speed riding. The downside is, you'll lose peak track speed. It's all about trade-offs: the gearing Polaris chose will be ok for most people, but with room for improvement in many cases.
Going back to the clutch itself, I have no doubt a properly adjusted P-85 will act like a lower gear, although mostly at engagement. That advantage disappears if you don't tighten the deflection as the belt stretches and wears though, and that's probably part of the reason Polaris added the bearing. This roller bearing delete should get some of that back, but I don't see it making a difference in the P-22's biggest downside (premature evacuation). If I had a P-22 and money to burn, I'd convert to P-85 - probably with TRS clutching - and forget about it (other than the usual clutch maintenance). Short of that, I can see taking your chances until the warranty's out.
