I've talked with several people who have had the splined adapter get worn 'cuz it's tough to make the tolerances tight enough to really stand up to street use. Basically, eventually the cog's splines and the carrier's splines didn't fit super tight, and the cog rocked back and forth, which just made the whole issue worse. I'd recommend against it. If you're changing your gear that often, a flip-flop might be a better option.
