I used <R,U> for a long time, but I eventually moved over to <M,U> for both the front and the back cases. It feels more comfortable. Obviously just for 3x3, not OH or big cubes, because that's just annoying.
Fun fact time:
I've been runner-up for Pyra every year at Nats since 2010 (5 years in a row). Unfortunately, I can't make it this year. So, congratulations to the person who gets second at Pyra this year. :P
We had a club at RIT two years ago (I think), but with people going on co-ops at different times, nothing materialized last year. There may be some interest for some get-togethers, but I think it's too late to apply as an official RIT club for this year.
