10/16 is a great setup. Watch some Benny Greb videos and you will be convinced.
This ^^^^^^^. But if it must be a four-piece, then 12/16 is the combo. Every time.Since you're already mounting your toms to cymbal stands that are there anyways, why not go 10/12/16? Or if you want to try something funky, go 12/10/16? You're only having to haul one extra drum at that point, not extra stands and such.
