This is a great topic Cam. I've been thinking a bit along these lines recently but it started more with my cockpit setup. I recently realised that my bar roll is significantly different to what it was years ago and that thought that this was realted to current bike geometry. I used to roll my bars forward to force me into a more aggressive over the front elbows out position. My bar roll is a lot more neutral now as I ride more centered in the bike. With that my brake levers are a lot flatter than they were too.
Lots to think about here.
