I'm currently learning the L perm (backward J). I've noticed that several PLL's can be done with only U, R, and F turns, and such algorithms feel natural to me due to fewer regrips. For example:
F perm: R' U' F' R U R' U' R' F R2 U' R' U' R U R' U R
J perm: R U R' F' R U R' U' R' F R2 U' R' U'
T perm: R U R' U' R' F R2 U' R' U' R U R' F'
Y perm: F R U' R' U' R U R' F' R U R' U' R' F R F'
I looked at the Wiki PLL page, and did not find any such algorithms for the L perm. Does one exist?
