So far, I float unless the kit came with a way to attach it, like the aforementioned board-mounted pots. I haven't done one of 'bean's boards yet, but I've done another pedal that didn't come as a ready to build kit. On that build, I was happy to have to float the board because I needed to debug and troubleshoot quite a bit. With a floating board, it was easier to get in and out. I may go back and shorten some of the wires to clean up the rat's nest look, but probably not. If it ain't broke, I won't fix it.
