Frame question from a NOOB
What are the advantages of a Full 4130 Cr-Mo Double Butted Alloy Frame set versus a Full 4130 Cr-Mo Alloy Frame set?
And is it worth paying the $70 difference?

Its also about aesthetics. If you like a classy look: go for double-butted, quill stem fixie. But if you want a more modern fixie then get the tooth-paste welds.

Bending stress occurs at the joints, not the center of a tube, thus material can be removed from the center of a tube. Look at this bridge, it is built according to the same principles. Lots of material at the ends, less material at the center.

I choose lugs over butt welds for similar reasoning. A butt welded frame has a stress concentration right at the highest stress locations. Lugs are better, less heat introduction, stress is transfered via a lug.
The reason more bikes are lugged $$$$, it's costly to use lugs.
