Distings are definitely feature-packed, but I find menu-diving on modules to be a pain in the ass. So much so that I'm considering selling my Plonk (well, and the fact that I really don't use it much anymore). Of course, having something like a Disting and setting it and forgetting it seems like a bit of a waste too.... The only module I really tolerate it for is my Ornament and Crime, which I absolutely love.
Personally, I would definitely keep Marbles, I miss it. Also... MATHS. I know, I know, but it, at least for me, truly is a useful module and it looks like you have room. One other suggestion - Folktek stuff is very cool, I've had a few pieces and still have a Nano Garden, but you might be better off with a Chronoblob 2 or something similar. I think they're less hp too. Just some random thoughts.
