B2 R' L D2 L' D2 B // 4a1 (12)
L U2 F2 D2 R B2 R

other:

(U2 B2 U)
(R F B2 R2 D2 F R) // 2c3
D2 R2 F' R2 B' L2 B'
L2 B2 U2 L2 U2 // S (22)
+1

F U' R' L'
U' F2 U2 D' B' L2 F' // 4b2
L2 D' R2 D'
R2 D2 L2 B2 L2 // E (20)
+0

this set of 4 dr variations seemed promising but I didn't find anything amazing
(F) R' F D2 B (U' D L' U R') // 2c3
(L2 U' L2 U' L2 U L2 D2) // S+E (18)

D' B' (L F' B')
(U B2 U2 L) // 0c3
(U) U2 R2 D F2 L2 U2 L2 U
R2 B2 U2 L2 F2 // E (23)
+0

0c3 swag
idk if i've ever found optimal on this subset lol

D2 R' (D' R')
(D') L2 U' B' D' // 4c3
(F' D2 F' L2 F' U2 B D2 B')
(R2 B2 D2 B2) // solved

lol I forgot to blocky fish i'm so fuckin dumb

D' B' D2 L'
(L2 B' D2 B' D) // 2c4
B (U2 F R2 F' R2 F)
(L2 F2 D2 L2 D2) // S (21)
+1

F R B F' L
F2 D2 F U F // 2c4 (10)
(R2 D L2 U B2 D' F2 D')
(F2 U2 R2 L2 B2) // E (23)
+0 -> 23

i tried F' B2 U2 L2 B2 U' F2 U but not F B2 U2 L2 B2 U B2 U on the 4b2 rip

(B) D F2 D F'
(L2 D2 R D) // 4b2 (9)
(D' U F2 U D R' U2 R)
(B2 U2 R2 B2 R2 B2) // M (21)
+0 -> 21

found this htr as 
B2 U2 B2 R' U2 R2 U2 R'
U' D' F2 U' D // M (20)
which is +2 but you can obviously do it from the other side and remove the 2e2e for a different finish with possible better slice. there's also
(D' U B2 U D L' D2 L)
(F2 U2 L2 B2 R2) // M (20)
but it doesn't +0

other:
(D F2 L, D2 F' L2 B D) // 2c5 (8)
didn't look at this because of the terrible corner setup, i didn't have many drs because i misscrambled a billion times and wrote a bunch of eos wrong
