I am considering a steel frame as a possibility for a badly needed new bike. The last steel that I owned was an old Ross back in the early 80's. What are the advantages/drawbacks of lugged vs butt welded construction on modern frames. As an example two frames I have been considering are the Torelli Countach and Mondonico Futura Leggero. Both made by the same company from the same tubing, same geometry but one pin-lugged and one TIG welded. Only about 3 oz and $150 difference. Thanks
