Of course the best looking dr I wrote down had a 20 that doesn't come from a linear htr:
L' B R B U2 L U' L U2 L //4A2 4E
Tunnel visioned a bit too hard on the R B2 R variation, which had linear htr in +5 but no good continuation.

Replace [] with (B' F' L2 D'), which is htr equivalent. Keep everything up to HTR, and replace {} with B2 R2 B2 D2 B2 for M slice in 19, which is +1 optimal.
