Coincidentally, the day before this was brought up here, I was just thinking about giving 750 a try on one of my bikes, down from 760. I stand a lofty 5'8". Both my bikes have ~450 reach and 40mm stems. I was thinking that it'd probably help speed up handling in tight, quick, steep corners, where my weight ends up further back. When I overforked one of the bikes to 170mm from 160, I feel like it made it handle better too due to the increased stack bringing the bars up.
Keeping wider bars for stability on a 170mm travel bike with 29 front, DH casing tires, and 38mm stanchion fork seems kinda excessive lol. I honestly don't remember the last time I was riding down something and really felt like bumps or rocks were twisting the front wheel off line. With modern enduro components, the front wheel is going to go wherever you point it.
