PLICA, welded ribs? Maybe you mean brazed? And even then I am not so sure that AYA are brazed.

The vagaries of ribs, here and in other posts, reinforce my convictions that ribs are an abomination.

Alex Martin showed the way with his ribless guns. If the looks of a ribless double are objectionable then make a top rib that is screw detachable. It is incredible that in the days of CNC tech (used by the very "Best" these days) we are still messing about with tin tech.
