who_else,
Well there are several ways to prepare your striker tip. I like to sand the edge off of mine, all the way around, and kinda give the tip a small radius. Then I will start using it on my calls and sand it back down to flat a little at a time until I find the right spot. Also your length can play a big role. If the striker is too long it can affect your sound. It' s kinda a pain until you figure it out.

I start with an onverall length of 8 1/2" and then cut back from there. I usally end up with a striker between 7 3/4" & 8 1/4" . Depending on the type of bell you use will effect overall length. Differn' t weights will give you differn' t vibrations.

Hope this made since.
