Well I'm mixing up my technique a bit now with a metronome on my computer, I'm now going RMIMR, not sure if thats going to help though but it may change, I've got the fast 16ths down, I never knew I had such speed in 2 fingers lol.
Ideally you want to work on different patterns. Get one down and then move onto another. You'll have some that you prefer more then others. For ones that don't seem to come as easy as you would like, practice a little more on them.
