I think that the asymmetry was definitely emphasized at 455, but I did notice it at 405.

If you work on getting your butt down, I can see 405 for a set of heavy doubles/triples.

If I were you, I'd start on doing sets of 5 with something easy, say 315. Only focus on form and keep the bar in your hands in between each rep (up-down-up-down...) so that you can touch and go and just think about where your body is in space. Then take what you learned to 365, 385, 405.

Warm-up, and follow it with:
x sets of 5 x 315 where x is some number where you're not getting too tired (I don't know you)
2 x 3 x 365
(1 or 2) x 3 x 385 <- focus on form!
and work up to
1 x 3 x 405

Can't wait to see updated vids!
