Holy sh!t . . these frames are the nuts

600 quid for a full custom build seems pretty good to me, and the quality of these frames is top notch, certainly a step up from a Bob Jackson

How do you know? Did you cut the joints up and analyse them or did you go by the paint and the "classy" graphics. All the ones I've seen look a step down from a Bob Jackson and about as classy as an Argos engagement ring.
