Regarding saw choices - is there a good reason to have both a dovetail and a rip carcase saw? For example the Gramercy line has both a 9" DT saw and a 12" carcase rip saw that is recommended for use for "larger dovetails". Has anyone compared them side to side and would it be reasonable to use the 12" saw as a primary dovetailing saw? My hands are big and the 12" saw feels pretty comfortable
