I play a four, five, and six piece sets on a regular basis. The four has a 10x8, and 14x12 toms. One of the five piece sets has a 10x9, 12x10, and 14x12 toms. The other one has old school sizes: 12x10, 13x11, and 16x16. The six is 10x8, 12x9, 14x12, and 16x14 toms. I believe all of the bass drums are 22x16. With playing the four piece I have to think more than the six piece. You can play the same patterns but you have to make sure that you won't run out of drums trying to get them out.
