Tradition, inability to fill spaces quite as well, less elegant, ?possibly harder to work with? Those are the things that immediately come to mind, but I am not a framebuilder, merely an interested enthusiast, so I am sure someone more experienced can give better reasons.

BTW, I see you are located in Cincinnati, I happen to be as well, in College Hill to be exact. You're one of the few fellow Cincinnatians I have seen on these forums.
