Re: Marks on tom heads
Generally speaking, light sticks don't make full sounds. Maple sticks are lighter but crack easy. Coated drum heads get marks on them when you play them. Nothing wrong there. It's the oxidation from the cymbals on the tip of your stick making the marks on your heads. If you have dents then that's different. That's a technique issue. You can't play a coated head and not mark it though.
The best way to do art, is to dispense with good and bad...and just get on with it.
