I always warm up with high bar and do my heavy work low bar. Weird setup, but it works for me and keeps my movement pattern solid.
I noticed high bar cleaned up my squat depth a lot. Low bar let me move more weight, but I was cutting depth without realizing it.
I'm in the minority, but high bar actually made my low bar stronger. Building my quads fixed my sticking point out of the hole.
Give each one 8-10 weeks instead of switching every few workouts. It's hard to know what's really working if you keep bouncing back and forth.
