I have the surly steel fork on my bean green cross check. I agree with Knotted that it's a really nice fork, both to look at and ride.

Consider mini-v brakes. I like them SO much better than cantis and they work with STI levers. Tektro makes some as does Campy. I have Veloce ones (on an otherwise Shimano mixed XT/Ultegra drivetrain). They stop well, modulate well, and do what brakes should do. One caveat: if you do get mini-v's, you need a barrel adjuster on your brakes or the quick releases won't work.

I LOVE my Cross Check and am sure you will too.
