U perms, optimal is R2 U' F B' R2 F' B U' R2, mirror/inverse to get the others, also the 11 move 2gen ones are good to know.

(R2 U' R2 f2)2 and variations

That was helpful! I noticed the insertion finder gave the same cycle in different variations.

You can also move the first move to the end and it solves the same case, so more opportunity to cancel

Scramble from FLIP Open 2017, two 24s found in 1 hour!
R' U' F L2 U R2 F2 D B2 U' L2 D B F' L' D' U2 F D' B L R D B R' U' F

24 #2
Finally, a 14 to 5c skeleton that I found at the end of the time (IF says 25 anyway)
Cool scramble!

I average about 43 moves with CFOP, blockbuilding and stuff like doing eo.
I am really lost right now with all these methods so can someone help me with what to do next.

Practice more efficient blockbuilding. Learn to do commutators and start finding insertions.
And, learn doing NISS! It can be an extremely helpful technique. Also pseudo blocks help a lot.
Speedcubereview's tutorial gives a nice overview of the basic fmc techniques. Definitely check that one out, it helped me a lot.

What's the process for finding cancellations for this type of insertion? I was able to cancel 1 move but it was mostly just luck.

I usually fix pseudoblock then continue, but instead I just kept going and it turned out to be a good choice. Also I actually did both p223 and AB3C in two steps(222 and 122, 122 and the rest) but IIRC there were 1 move cancellations in both of them. And IF says my insertion is optimal. Basically had a stroke of luck, I should say
Now I'm curious if there's any better continuation... I'd appreciate it if anybody finds it

A very nice set of scrambles!
does anyone have a good list of commutators i can use for fmc? I just got into this and im starting from cfop, and as it is known, cfop is pretty bad in fmc. all i know for edges is u perm (but i do know the optimal one) and all i know for corners is a perm.
