I definitely like floor toms a lot!
My favorite is 14x16. I get better tone and cleaner multiple strokes, but still the same fatness as the 16x16.
I always use 3. one on the hat side, and the usual "2 down".
I have been known to use 4....but honestly, if I had the room I'd have 3 on each side (like a L hand, R hand 14-16, 16-18, 18-20).
OR, I wouldn't mind 14-16-18 on each side with my 8x12 rack tom.
Darn that stage space!!!
Here's the 4 floor toms (Left side)14-16, (Right side) 16-18. I did use them all.
Right now I have a 8x12, 12x 14, 14x16 set up with a 13x15 on the hat side.
