B' L B2 R2 F // EO
(L2 R' B2 R' D2 L D) // DR extension (M2 at start of line)
(R) L' // HTR in 14
F2 D2 B' F' R2 B' F // Solved in 21!!!
There was a LOT to check from this start given the nice HTR subset along with a very easy to manipulate EO
I found this cool HTR for example:
B' L R2 F B D2 B' , L (R F2 R' U2 L U , R)
Also had two different 9+4's along with a 10+2c3 and 10+2c4 but didn't find much there

Found this other DR but too late to use it :/

DR start is 21 optimal so this shows that my recent 6+ week break did a lot of damage to my skill XD (none of the 4 total 21's seem easy to find TBH but with that many 21's it's unlikely that 22 isn't findable for a human here)
