I had a few minutes and found two one steppers........

Quote:
UAUR(24)r78c28[(1)r7c8=(8)r7c2]-r6c2=(8-1)r6c4=(1)r5c5; r7c5<>1=4
or
w-wing(24) plus transport: (2=4)r9c6-r4c6=r4c1-(4=2)r5c1*-r1c1=(2)r1c3; r9c1*, r9c3<>2

I used the UR 24-24-241-248. The 1 forced an 8 in r4c3, creating pincers; r6c2, r7c3<>8.
