LP Performer Series

I have 3 LP performers Series My Dad got me awhile ago at guitar center. It was either Performers Series or Aspire
. When I first got the I noticed a ring from them. and I know that PS (performer Series) is 2 ply cheap asian oak and dog chewable water buffulo skin, but its better than Aspire. So I got Remo Crimplock skyn deep heads and confort curve 2 rims, the ones that go on the giovanni congas. so the sound improved but I want a "old school" sound and right now I cant afford new congas. Whats skins on be great for these 2 ply drums? should I get Traditional rims? And what is you take on PS congas or Sam Ash Caliente and ardiente series? How can I make them sound better? I know about technique and hand position, that I have. but How can I improve these drums of mine?
