I'm a big guy. Nearly 6'3" and I weight about 300 lbs. I've always had to use a 4 legged, very sturdy stool for a drum throne, because after playing crashes or major fills, I'll thrust up with my legs and feet, losing complete contact with the floor and the stool to catch my crashes. It's not always such a dramatic jump. I guess it depends a lot on where my cymbal placement is. I've seen a few other drummers do this. Does any of you do this? And if so, do you have reasons?
