Just learn 7s at around sub 8,also dont watch the cubicles video about tommy learning to tymon, its Bpaul 7s flip, which is one of the baddesr variants, and siccess rate with bpaul is also pretty low. Just learn tommy, and i know the last 2 ateps arent that easy, but once you learned it its very easy, improving with memo is just keep solving.
Also with flip, try to inspect the whole first cross and use this pin order:
DR (match C to U)
UR (Make an L shape with C, U and L)
UL (match the L shape to R)
U (Make the whole cross)
Corners: doesnt matter, i do dl ur dr ul.
Also do an X2, its faster than a y2.
