Surprised nobody contributed yet

I could only find a W Wing 12 operating on 2s in col 2 so r3c1 becomes 1 stte

Looking again I find that the W Wing is available immediately and sets r3c1 to 1 which according to draw/play converts the puzzle form V hard to Medium!

X-Wing on 2 in r34; r12c8, r57c1 <>2 opens another
X-Wing on 1 in col 19; r7c3 <1> - 1 r7c3; stte
Can also be eliminated by a chain:
(1=7)r7c9 - r3c9 = (7-2)r3c8 = (2-1)r3c1 = (1)r1c3 => - 1 r7c3; stte

I didn't follow through enough on this puzzle. I saw the W-Wing and got lazy when I realized it wasn't a one-stepper.
