Hmm, that is a hard decisions...I know some friends were looking at Yamaha's and their complaint was that Yamaha has, evidently, changed it's hardware line a bit, and they said they didn't like the new hardware at all.
I played Yahamaha Recording Customs for several years, and I had a set of "
Stage II" drums that I used for general playing (There's no way in hell I'd leave an expensive drumkit in a club overnight! Equipment sprouts legs too easily.)
Personally, I'd go with the Pearls....just because I prefer their hardware. I use all Pearl hardware (everything but the Kick pedals and Hi-hat, those are all Axis Longboards.)
AT those levels of drums, the problem to me is the shells are all essentially the same....it's the hardware that makes the real difference.
The only thing about the PEarls, if you do decide to go with them, I would change that el cheapo "isolating" system that pearl uses...that looks like a Rim warping piece of crap....it was not a good idea....I'd rather have the tom mounts mount to the shells than use those things....so, I would upgrade to their better line of tom "isolation mounts", but that's just me....you may find that they work just fine for you. (Personally, I don't like any of the isolation mounts that are out there...I don't think it makes that big of a deal, and in a live mic'd situation...they can make problems for you....especially if you don't have noise gates. Just my opinion.)
