I have a Luna and a Fly. I'd say that if money is any object at all you are ahead of the game to get the Tetra and better parts. Craig is very proud of the fact that all his bikes ride and handle the same. The price differences are based on materials (boron/carbon is big $); labor time (Tetra is handwrapped); and weight. Otherwise they ride the same. If money is unlimited go with the latest and greatest. They were the number one bike under custom frames in Velo again.
Anyone who commented on Parlee has liked theirs. They would have to go a long way to have the service that Calfee offers. You can give Craig a call and discuss you concerns and needs. He will give you a very honest appaisal and answer. The first time with the choice of Luna/Tetra and my situation then he said Luna. I find last EST is usually a good time to reach him.
