Cymbal stackers can give you cymbals you want in a smaller footprint. I learned to tailor the kit to the amount of stage I was allocated.After finally getting my drums outfitted with decent heads, tuned to my liking, and accompanied by neurotically selected cymbals, I realized that the set is just too blasted wide.
No, I'm not a believer in those modern mini-sets, and passed on one because I didn't like the way it sounded. I also don't believe that saving a few inches of space is worth it. However, my gigging experience taught me that minimizing the footprint of my set is wise, since lots of times I've ended up on a "stage" not much bigger than the bed of a pickup truck.
And there's not a lot drummers can do about the depth of their footprints. The distance between the throne and the bass drum pedal is pretty much fixed, and while a shallow bass drum may save a few inches, the cymbal overhang may almost negate the space savings of a shallow bass drum.
But width, at least in my case, seems modifiable, and my problem is two rack toms. A second rack tom puts my ride cymbal fully a foot farther to the right than a 1-up 1-down setup would require, and this foot actually increases my total footprint by about 25% as calculated by square footage. I can't conclude that a second rack tom is worth this increase in my footprint, and definitely don't want to position my ride cymbal high and over the rack tom. Ergo, I'm afraid that I'm going to have to get rid of a rack tom.
I admire drummers who play different configurations for different occasions, but I'm too much a creature of habit to do that. I like to be so habituated to my setup that I don't need to think about it, regardless of the occasion. It therefore looks like I'm going to have to get used to a 1-up 1-down configuration.
