This is bit off subject, but its worth telling. An old drummer friend of mine used to have one of those old cheap 3-legged drum stools that was broken...the seated pad part of the stool would come off...when you sit on it, you would have to balance yourself or you and the seat would come crashing down....pretty dangerous stuff. Well this guy refused to buy a new stool...I guess he thought it was some great achievement to be able to jam and balance himself on the stool at the same time. Anyway, I guess there is something to be said about finding a stool that you're comfortable with and will allow you to balance your weight evenly. Personally, I like a good stable round stool that can swivel, but keep me evenly balanced.
