Hello everybody.

I can solve the cube with corners first almost always under two minutes, my record being 1:13 once I was lucky. I have also times of 1:19, 1:20, and 1:21, nothing new, I know.

I use this "foolproof" solution which basically involves four algorithms and a fifth one I learned elsewhere.

This algorithm below is to put the corners in the correct place. It has to be used once or twice.

U-1 F U L-1 U L U-1 F2

This other algorithm below is for putting the corners in the correct position. It has to be used from one to several times. I am aware there is a set of seven algorithms to use the proper one only once, but let's leave that for now.

U-1 F2 U F U-1 F U F2

Both algorithms require the solved corners back an the ones to solve in certain positions in the front.

Now the issue comes in. I tried to switch to Roux and I want the pair of two algorithms for solving the corners, which has to be different from that pair above since the first algorithm removes one edge from one of the 3x2x1 blocks.

NOW THE QUESTIONS

Could you experienced cubers tell me which are the two algorithms that suffice for Roux corners and that don't mess up any of the 3x2x1 block edges, even if those algorithms have to be executed more than once?

Bonus question:

Is there any pair of algorithms that preserves the second algorithm which doesn't mess up edges but adds another algorithm for placement as the one for orientation I have works?

Feel free to have a look at the website I linked if you want to understand the two algorithms I mentioned better.

Sorry for the long message, but I hope it is at least clear enough. Two sufficing algorithms for Roux corners, if possible keeping the second one above.

Thanks in advance.
