F2L With Minimum Cube Rotations

[irontwig]

Just practice your F2L slow and before you do a rotation think about if it's necessary or not.

Scramble the cube with only L, U, and R moves. Solve the f2L in that same fashion. This will help you see what can be done with and without cube rotations/F,B moves.

For lookahead, follow this tutorial.

Using full Fridrich you should be able to be sub 20 just by practising. Maybe you need to solve the cube slowly but continuously. I would recommend you to use a metronome. According to my personal experience, the obstacle for the 40s wall is looking ahead. You should learn how to look ahead.
I used to stuck there to, but after practising using the metronome on my look ahead, I can be sub 30 now.

You are definitely correct, I think you and I share the same experience. I'm stuck in 40's and it's definitely my look-ahead skills. I started to do them slow over the past few days and I'm getting used to looking at the next corner/edge pair midway through the solve. I'm definitely going to incorporate the metronome aspect next time. I'm still trying to minimize my rotations though, I'm starting to use more l/r/d (small letters) moves to get around this. By the way, does a "d" move count as a rotation?

For the question earlier about the tension settings on my type-c with a c4y core/springs, yeah, I got it tensioned right!!! No pops and cuts corners from about 45 degrees (slightly under). This is way better than my type-a which pops more than Orville Redenbacher's popcorn

"d" is technically a cube rotation, since the center pieces physically move, and I haven't found that it's any faster. I find d and d' quite clunky, actually. I'd rather eat the rotation. And if you have to do a whole bunch of d's, you haven't solved the basic problem.

Here are a few tips that helped me:

- Don't always go after the first pair you spot immediately. Another might be easier to insert. Often this causes the first pair to flip in such a way as to no longer require a rotation when you get to it.

- Sometimes you can partially set up a corner-edge pair without rotating, then rotate to finish them off. This avoids cases that require TWO rotations, which are awful.

- Don't be afraid to use the odd F move here and there.

You can't usually do F2L with only L, U, & R though. Although when I do F2L I usually only use R, U, l, & x, cross on left is very finger tricky, the look ahead just takes some getting used to.

I would recommend you to use a metronome.

do you mean, that type that looks like a pendulum that makes a sound every two swings or something like that?

It will help with look-ahead, basically, set the BPM to where you can move once per beat, it will force you to look-ahead. As you get faster, simply increase the BPM.

Good luck!

whats your cross time? because if its over 6-7 seconds you could work on that too

Yeah you are right, it is a little clunky...thanks for the tips, I'll try them out and post my progress.

You can if you scramble it with such moves.
