sandbed, stay or go?

IMO, the whole buffering thing is an advertising gimmick. Since aragonite needs pH values much lower than the tank water to actually dissolve, it isn't really doing any buffering, at least not in any appreciable amount.
And if you're going to run a SPS dominated tank, you need to supplement anyways, either with kalk, a Ca reactor or a 2 part solution.

true i supplement with kent liquid reactor and for alkalinity i use seachem alkalinity buffer either way, so no big deal. ya i do have a reasonable amount of flow always shifting my sand around, i can't say it's damaging the corals in anyway, i would just assume that an sps dominant tank would benifit from very little to no suspended particles, and i know that frag tanks always look so pristine. my main worry was whether my alkalinity buffering would plummet because of sand removal, but since i constantly supplement regardless shouldn't be anything of a problem

Have you considered replacing your current sandbed with a new sandbed of coarser grain? Then it wouldn't blow around so much. What kind of sand do you have right now?
