Ok i have remo pinstripes on my batter head and still have the original yamaha batter 188's (they are resonant heads) that came with my drum kit. Ive had the kit for 2 years now and must have tuned the resonant heads once, barely. I was just wondering if 1) I should change the head (the sound i get is ok...could be a little better) 2) If i have to change the heads which ones would you recommend 3) should i be tuning them more often??
