OK, I need a little advice here. I'm building a bop kit from some orphan drums I have lying around. I'm using a 16 x 15 floor tom as the bass drum. I want to drill the shell and mount a Pearl tom mount on it so I can use it to mount one tom and one cymbal. My question is where should it go? How far from the front of the drum should I put it? I'll start with a 10 x 8 mounted tom and never have anything larger than 12 x 10. Any help would be appreciated.
