only other workable DR：

L2 B2 U2 L R D2 F2 L R' //E  22   +3 bro💀

Find this kinda late because I almost forget this rzp(??? no idea why)
and missed a 22 opt which is not fancy at all(??? no idea why again)

R2 F2 L2 F2 D R2 F2 R2 D2 F2 U2 F2 L2

EDIT： E in 22 is actually +2 IDK I counted it wrong or missed it(??? no idea why X3)

(R2 U' B R'，F)   //rzp4c4e  2p
F2 R2 U D F    //DR  10+4b2  6E
(L2 F2 U F2 B2 L2 U')  //HTR inserted S2
(B2 D2 R2 F2)  //Fin    4-1/20


also this interesting BB-DR mixed solution：

(B U)//rzp 4c4e in 2 wtf，but this case looks kinda hard
(R' F R)  //2x122，try some bb but also rzp 3c2e in 5，and finish dr won't break any block，nice
(B' L' B' L')  //DR  9+4b2  2E
(U2 # B' L2 B)  //straight to trigger but fake htr， but wait a second
(U2 D2) //L3C  in  15 wtf again

however I can only find 8-1
#=U' R' U L2 U' R U L2

nothing better than 22 was found with real htr too

opt for this DR is 21 with 4qts
best 3C insertion gives the same 21

(L' U B) L2 D F2 U2 L B2 R   //DR 10+6c3  4E
(D L2 B2 U' L2 U)  //HTR not good

(D' R2 U' F2 U')  //Fake HTR
Flip：

(L' U B)L2 D
(D' R2 U' F2 U')  //DR  10+4b2
(F2 B2 R B2 L)    
(B2 # L2 F2)    // 18 2E2E
#=U2 F2 D2 R2 B2 D2 F2 L2   8-5/21

tried switch side after dr but seems very far away from trigger，so switch back to check tons of variations....Luckily first variation gives me this direct 21  ：）otherwise I might get DNF


other：
nothing really good，best dr 10+4a4 opt gives 22💀
