I have a really really long torso, so I already prioritize upper and mid back to make up for the really long moment arm when deadlifting.
The tightness in my hips can definitely be a blessing when squatting, I just feel like it can't be good for me, and I get a really nice bounce out of the hole when squatting Olympic style.
As far as bench, I have a solid arch. Scaps stay retracted, but as soon as I get about 4-5 inches off my chest, my elbows come out of the tuck and start to flare. I think its a shoulder stability thing and will really be working on it. Wrist wraps are a good idea, but I'm going to try other means first.
