... I also don't enjoy 65% layouts so I guess that's probably part of the cause as well
My true 60% Alice has really done wonders for me with left space bar also held down to get to layer 2, my numpad layer. Y,U,I=7,8,9, - H,J,K=4,5,6, - B,N,M=1,2,3 - right space = 0 - Right Alt = "." etc...
The Alice split creates enough separation where I don't need to be a particular muscle memory wizard to figure it all out.
I also have an HHKB, so using "?" as down arrow, "[" us up arrow, with Fn key, etc... is already second nature for me.
