As a curiosity, the puzzle also contains a relatively rarely seen (or mentioned) pattern:

iW-Wing: (4)r2c2 = (4-9)r5c2 = r5c9 - r2c9 = (9-4)r2c7 = (4)r1c8 => -4 r1c1,r2c7; stte
Of course, in this case that's redundant, as this would do:
L2-Wing: (4)r2c2 = (4-9)r5c2 = r5c9 - r2c9 = (9)r2c7 => -4 r2c7; stte
