I altered my drum set two days ago. Here's a closer look:
I moved the second snare drum over to the side of the high-hat, then placed my crash cymbal besides my thin crash cymbal. This allows for easier access for the to the crash, since before I had placed it above and between the second mounted tom and the ride cymbal. Now it is much easier to alternate between the two, so I can create a sense of color in the cymbal crashes. the second snare drum also allows such alternation between the color of the instruments, as well as making it easier to move between the high-hat and snare drums.
Oh, yeah, and I stuck my conga over by the floor tom. Still trying to find a way to work that thing more easily into the kit.
