At last! I finally got my first sub 30 FMC solution. I am really happy with this solution, especially since I was able to get to AB4C in just 21 moves. The scramble was from the Weekly Berkley FMC, so in case anyone is going to do it, I put it all in spoilers. I got this yesterday, but forgot to post it in this thread.

Also, I do not know if there is anything that you see that I should have thought about with this solution, but if you have any thoughts, I would be more the happy to hear them.

Spoiler: 29 move FMC Solution

With your start I can get a slightly shorter skeleton (with the same number of unsolved corners) but the insertions are actually worse.
