Whether 6 1/2 is too heavy to carry all day depends on where you're carrying them. No problem for pheasants or prairie grouse; too heavy for grouse and woodcock, IMO. If I can shoot a 5 3/4# 20ga as well, why do I want a 6 1/2# 20ga--unless maybe I'm looking strictly for a target gun? In which case I'd probably look for something with longer barrels, and maybe choke tubes.
And Wild Skies, you're right: the 28ga Repro is the ticket for the grouse woods.
The main problem with Crosnoe's Repro is that it's missing a trigger. If you don't mind that, I'd say good price.
