PLL H perm

S (R U2′) (R2′ U2′) (R2 U2′ R) S’ (a headlight at any angle)

Finger tricks: over turn the last R (marked in red) by right index finger. S’ by left index finger, holding F-slice by right thumb and index fingers.

I was using the typical algorithm M2′ U’ M2′ U2′ M2′ U’ M2′. But I sometimes made mistakes in turning M2′ with my left ring and pinky fingers (double trigger). So, I changed it.

Even the current method has 2 moves more, I found it more reliable and adequate for me.
