what are your tom sizes? Mine are 13 14 and 16 for the floor tom. In your opinion what size would be a good addition to these? Sure, I can tune a drum to sound however I want within limits but what would be a nice complement to the ones I have? I was thinking maybe a 10.. any opinions?

I think a 10 to the left of your 13 would be pretty good actually. Depends on your budget and what kind of sound you're looking for really

I would have to say a 12.
I have all those size toms and let me tell you the tunning diffrence between a 10 and 13 are pretty sinifigent.
so if I were you I would really look into it and the kind of sound that you are wanting out of your kit before you add one on.
