I was on the Ergodox Ez for many years which is also quite big. I was unhappy with how much space it took up on my desk. I switched to a Totem keyboard, a 38 key split, and while it took a while to get used to and feelings of doubt, I've eventually become very happy and settled on this keyboard. It pretty much solves all of my needs and I don't have too much interesting in further experimentation. I did want to try the 360 because I like the key wells, but was put off by the size of course. But I did discover keyboards like the Skeletyl which I was tempted to try. Maybe something like that or a dactyl manuform would interest you?
