So, I've had this 18" ZBT (don't say it) China since I got this first drum set of mine. It was used and had some minor cracks all around the edge, being a bit of a noob, I never payed any mind. Then I learned that cracks get worse like this http://img101.imageshack.us/img101/8130/img3890t.jpg so I drilled holes at the end of the cracks. My question is, would it be better to cut off the entire outer 1-1.5 inches or just keep drilling them for as long as I can. I just recently put the first crack of my own in there. As you can see, there is one king-daddy crack that's bigger than the rest.
