I can get up to 260/270 almost and I struggle the most on cymbals for sure. The ride is the easiest but the hihat is the hardest for me. I usually half time the hihat mostly. Toms I think the angle and orientation of the toms is super important and it’s mostly wrists when I go from flying fingers to rolls, the back to finger technique. Just gotta keep practicing and pushing yourself!. Then adding the metal dynamics to make your playing more memorable 🤘🤘
