I have seen a few different charts offering different definitions of what are "FAST, standard, traditional, etc" tom sizes. My OCD yearns for clarity (surely there is an ideal, golden diameter-to-depth ratio?!?), but I guess there is none to be had, yet. As others have mentioned, it probably also depends on ply number and thickness and wood type and hoops and bearing edges and and and. For me, I have 12x9 and 13x10 toms mounted on my 22" bass drum and I wish they (or at least the 13) were an inch shorter (and I'm 6'2"). If my bass drum was 20" these toms would fit better for me, but likely look too big.
I have a 16x16 FT and I agree with ArtStar--what's up with that?
I do hear more and more drummers preferring shallower bass drums. I think 22x18 will become an increasingly rare size as manufacturers catch up to trends.
