OLL29 (Thunderstorm shape)

M U (R U R’ U’ R’ F R F’) M’ (vertical thunderstorm shape & a discontinuous colored corner is on the back side)

(R’ F R F’) (R U2′ R’ U’) (F’ U’ F) (vertical thunderstorm shape & a discontinuous colored corner is on the front side)

The first one begins and ends with the same turns as of OLL42 (M U…M’). And it contains algorithm of OLL32 (T shape).

For the second one, I was using R2′ U’ R F R’ U R2 U’ R’ F’ R, but the above mentioned one is easier, so I changed it.
