bro, that's a very good question...even the pros' are having second thoughts about it....
well, i like the Pearl more so stay with Mapex and sell me your Session...
(same joke with S' Peeves)
kidding aside...I'd still go with the Pearl Session Series specially the 90's model.
it was said that the wood of the 90's Session is good for tropical countries...it goes well with the heat and humidity here...this is in terms of the consistency of the sound. and that's what we use in our church.
this info was given to me by our AM church drummer, sa PM kasi ako...anyway, he said that back then when they were to get a drumset from Yupangco, he did a quick research from the web, and he got the same review from different sites.
he was down from choosing either a Masters or a Session. i know, alot of drummers here would think that he should've gone with the Masters..but because of the influence of the review, he then chose the Session. Either way, I can say that our church is blessed with a decent kit.(sorry for the OT..)
my apologies for the long story, i just want to justify my answer for you bro....hope this helps!
