It's best to rotate and insert than to regrip and use awkward B moves.For the case above I want my alg to be B’RUR’B
It's not that good of an idea to aim for rotationless solves with CFOP, if you really don't want to rotate use ZZ or Roux!
"Solving F2L cases from all angles" means:
- not rotating when you don't have to (oriented edge), even if it means using your left hand
- with above point: never rotating twice (y2, y then later in the alg y or y')
- when you do have to rotate, rotating so that you solve a back slot rather than a front slot
Edit: wait I realized you're talking about solving FR slot here, not BL.
Forget what I said, I don't have a good alg for this either (I use f' L' f to pair the edge and corner, then insert with R U2 R')
