Nino, what size sticks are you using? The bead will make a huge diffference. And like BBD stated, single ply heads on toms is a no no in most cases unless you want that real open hollow sound for straight ahead jazz. I hit hard when I'm playing Pop style music ( R&B, Rock, Hip Hop, etc ). Gopsel too. I may dent them a little over time, but not to the point where I have to change them every week. Are you using G1's on your toms? If so Switch to a 2 ply head. It may help, but dents happen Lil man.
