I just about got away with the chainline on a similar type of build-up. 135OLN Goldtec meant chainline of 46 or 47, and I had a Truvativ DH single ring set up at the front, but only just squeezed a 38t ring on with about 1-2mm chainstay clearance. It was quite a stiff Columbus frame, and there weren't any tell-tale rubbing marks on the chainstay paint. I think my chainline was about 2mm off, but not a problem.
I was using 38x14 on the road with 26" wheels, 38x18 singlespeed, and 38x15/16/17 fixed off-road depending on the type of ride.
