Maybe someone has already discussed this part, but I'm against racks simply because if I go to a gig by myself, and have to move stuff by myself, after setting up a rack, moving it would require at least 2 people depending on how big it is.
I, of course, discovered this after I had bought a rack and set it up, and then was asked to move everything on stage a bit. Toms and cymbals get really heavy when they're all on one thing!
Over time I've downgraded my kit to a Charlie Watts kit with old-style
Ludwig flush based cymbal stands. It's nice to have all this light stuff!
