Your second solve is pretty nice too, did you also try to approach the 6 move L9E skeleton directly? The new IF gives a 21 for this.

That was the first skeleton I wrote down, but I didn't try inserting it during the time limit (9 edges are bit awkward, and the other skeleton looked nicer). I tried it for the no time limit challenge, but I didn't get anything better than 25 or 26, I don't remember.
