Fortunately the first variation I tried. Edit: it's the only sub 22 from this set lol

Note to myself: check 2+2 on both sides, don't miss obvious drs

I got baited by this:
(D F' U B2 D') // blocky eo af
(R' ^ B L' B') // 5q (9)

Somehow missed 2c3 2e in 10 from this eo

Bruh, so many findable sub22s here

How did I miss

I had a 23 from this dr but then I randomly tried 3move blocky setup to "J shape"

F2 L F2 B R' F // 4a1 2e (11)
L F2 B2 R B2 R // HTR (17)

This is just (U' R U) -> (F2 D' L D) ext of 10+4c3. (B2 U' R U) gives 4a1 4e (11) but I couldn't find anything there.
Bro, forgot to switch (U) U' R2 D' - F' which gives a 2c3 4e (10) and an easy 21

(U L)

B' R2 B' // HTR (15)
[R2 B2 R2 F2 U2] // E slice (19)
[] = U D' F2 R2 F2 L2 U D // solved (21)

this is just an extension of
L (R' F D2 L) - (U) R2 D2 B' F2 D // 4b2 0e (11), which has an htr in 14, 2e+slice sth sth into 22 backup. 

You can actually get a 20 from this rzp by doing +2 ext:
L (R' F D2 L)
(U') U2 B2 U2 R2 D2 B' D // 4b2 2e (13)
B' R2 B' R2 B2 R2 F2 // finish (20)

U (R' F' D)
(L2 U2 R2 L' B) // 4a1 4e (9)
L' (F2 [L D2 B2 R']) // HTR (15) and 2e+s in 17 so
[] = L' B2 R2 U2 F2 L' U2 D2 L' R // finish (19) sliced live

([U D]) B' U 
F2 R L2 D2 F L2 F' // 4b2 2e (11)

This was satisfying.
Edit: I knew there was some shift magic sub20 but I just couldn't prove it. 
Tbf I didn't know you could shift this like that

(U2 D R) 
(B2 R2 B2 D' B') // 4b2 4e (8)
B2 U (U' L2 U F2 R2 F2 U') // HTR (17)
(D2 F2 L2) // finish (20), slice in 19 but no +0

Quite mad at not finding the 19 but also mad at these 8+2s with multiple slices in 19 and 20 and only one working well.

I went all in on this group of 4b2s in 9/10 hoping for sub 22 
And I somehow missed the rzp for the 21, only did 4c6e dr in 10 :(

Fun fact: first time in my last 102 solves (since I started tracking carefully) I've used 2c3 6e in a final
