I still use non advanced f2l; is there a way to know which of my solutions is slow? my general feeling is that the cases where I use two cube rotations is too much and I should ideally try to limit those.

Also, for theory purposes, is there a list of all possible f2l cases? that is every corner location, every edge location, and every slot to insert to and every free slot combination.

I would just check your algs up with a reliable list.

Two rules of thumb:
1. At most one rotation.
2. At most 7 moves (not counting AUF at the start, not counting rotations). Note that two triggers with an AUF in between is 7 moves.

There are some F2L cases where the ideal solution is to break one of the two rules above, but most of them fit the above.

since I cheated and asked two questions in one post, I'm gonna ask it again here

Is there a thread to discuss how people would solve a particular f2l case or do you just post here?

What is the best way to identify COLL from any angle?

Use something like hyperorientation or just learn the 4 angles for each 2 sides of all the colls?

When I identify COLL I put it in a specific angle, that sometimes result in a U2 + U2 before applying the alg :confused: :?

If I’m not mistaken, you should only have to look at 3 non-last-layer colors to recognize it.

If this was your last white edge insertion to finish the cross, what is the best alg/move to insert it?
