Hey. I have some Meinl Headliner Congas in 10 and 11 inches... I noticed with alot of Meinl Congas, even the highend ones, that they are pretty ringy..My guess is the heads. I was wondering if I should buy some higher end congas or if changing the heads on these congas would help alot. If so, which heads should I get? Evans? or the Remo? Thanks for your time.
