- 1983 called and they want their song back.
- It's not serious enough to be a problem but you're flexing your (mid?) back at the bottom. Not a lot, but you don't have that rock solid, same shape throughout thing going on. If you've been doing ss for a while and this isn't your max then you can prob control that w/ pushing your knees out and/or just keeping your back tighter. Something to consider.
don't really have a statement on your other points.
