I would disagree. Fit is most important, other wise your constantly trying to adjust fit to point properly. In grouse cover, you don`t have the time to do both at the flush.
Lots of talk about shooting and owning multiple guns. IMHO, that`s a mistake. Had a good friend like that. Was always cycling through guns, and dogs, to find the "right" one. Never did. I own many rifles, but only one shotgun, a Winchester 101, IC and Mod. It fits me.
OTOH, if you just like to buy shotguns..get as many as you can.
