I love 15” floor toms but 16s are easier to get bags and heads for.Sometimes the 16" FT is harder to tune than a smaller tom, bad tuning sounds like tymp, but when you get the optimum tuning point you cant not love it. I feel that 14 FT sounds more like a Power rack tom that a FT, maybe for the round sound and less attack that 16 FT.
I've never played a 15" FT, I'd love it. Neil Peart almost always played a 15" FT.
I play 10/13/16 and love it.I know the 12/13/16 is a common setup, and even some 10/12/16 sometimes. It seems like a LOT of people default to the 16" FT.
I can't stand em. Might as well be a 70" floor tom IMO. They're just HUGE and hard to tune and even when I have them tuned up right they're just too deep and too flabby for me. And they seem physically huge. Might as well be a kick drum, or a timpani.
So I go 10/12/14 if I'm using 3 toms.
Does anyone else prefer to go no bigger than 14" for their floor tom?
(edit: the ONLY think I like about 16" floor toms is that they give me a place to store my sticks without them rolling off the drum - but I have to believe their are cheaper, more energy-efficient means of storing sticks during gigs and practices and such.)
