In a set up like 10, 13, 16, they'd be fine but I hate when kits are 10, 12, 13, with 14 and 16 floors. As big and clunky as 13's are for rack toms, I'd rather just have a slightly shallow 14" rack tom.
AMEN!!!!I'm a big fan of even intervals as it seems to make tuning much easier for me. If I want 3 toms, I go 10/13/16 and 10/12/14/16 when I need 4. My theory has always been to buy all the available add on tom sizes when you get a kit if possible. Everything will be discontinued and finding one later on is difficult.
Ringo Starr actually invented the 40" bass drum for set use. It was later retrofitted to a stand, and lo, the first orchestral bass drum was born! He was also a big fan of 4" and 6" toms, I hear.My bad, I really thought he used a 24. At least I did not say he used a 26 or 28!
