I actually finished ROLL a few months ago and it is SOO worth it. I average mid 9, so I think that it'll really help you. All of my PLLs have headlights on the left.

If you don't know what it is, it's basically a technique where you predict CP during OLL (as well as where the headlights will be if the PLL is going to be adj). I'm going to switch all of my adj PLL's so that headlights are on left.
Here's a video explaining this technique:
