There's exactly one 19 from this skeleton/DR according to NISSY, ran out of time but it's not easy to find

Other DR's I had:

D' U L U' R (F B2 U2 B' D2 R) 11+2
F' L' B (B' R U R2 F D' B) 10+5 :(
(R D' R) B2 D' B' R2 D2 B L 10+3
(B2 L) D R L F2 D2(w) F U B2 U 11+3

I think this attempt is a PB for most 2 move to 8 bad NISS EO's found lol. All were a result of some other axis indicating another EO on another axis using the FB (F B) = R L (R L) stuff. I didn't have time to check (U) D2 B U D or D2 F (D F B) but everything else got at least one look during the hour
