If I'm not able to try it out, I think I'm going to chance it that a 56 roller and a 56 crosscheck should fit about the same. I enjoyed riding a 56 roller more than a 59 so I'll go for a 56 crosscheck.
Any minor differences should be easily fixed by playing with stem length, seatpost layback and saddle positioning.
Or 56.
