65% is the sweet spot for me. Reaching across a numpad for a mouse aggravates my RSI. I ditched 100% long ago, then eventually ditched the mouse and moved to a laptop-style trackpad in the middle, which did the trick.

Over the years, I tried pretty much every keyboard with a built in trackpad. Usually the keyboards were so-so to poor. Eventually I got a plate of 6061 aluminum, added a nice wooden wrist support with routed out space for a trackpad, and built my own keyboard tray so I can have my pick of keyboards. Now I use a Ducky with Cherry Ergo Clears and couldn't be happier.

The dactyl keyboard family with built in trackballs are way nicer than ones with built in track pads at least from my experience. My personal favorite so far has been a Charybdis from bastardkeyboards. Expensive but I don't need a mouse anymore for being productive.

		Hah, 2 minutes before my remark. I feel like if anyone has 2+ ergomech keyboards, they should really try something with a pointing device. It's clear they don't mind having an expensive hobby :D

		That looks really nice! I haven't spent much time with split keyboards, particularly the extreme ergo things like that but I am very tempted!
