I've recently been changing a lot of my OLLs, not to get better algs, but to get better orientations.
It occurred to me that the first thing I do when I see the OLL is look at the stickers on top (I then know which group it is) then I look at the stickers on the side to work out the exact one. It occured to me that if I had the same orientation for all the algs in a group (such as lighting ones always being on the left, or Knight Move ones always being horizontal with the corner pointing down), then as soon as I knew the group I could AUF to put it into the correct orientation, and while doing that I can work out which exact case it is. Which should save time (at least for someone who's as slow at recognition as I am).
