I’ve really come to love the 20,12,14 size for my gigs. (Cover band everything from STP to Johnny Cash and all in between!). Some times I add a 16 floor Tom to the kit for more bottom but I find myself doing the Buddy Rich thing and use it as a table to hold stuff. Sizes are very versatile and the bass drums I use have beta 52 May mic systems installed and the things sound like cannons. I don’t feel the need for anything bigger as far as a bass drum goes! Sound guy likes my DW collectors kit as opposed to the DW Performance kit but I only use the Collectors kit for inside gigs.
