I bought the EII last fall just before the season started, and i must say it's an awsome piece of machinery. I did change the drop and cant while patterning to get as close to center for how i shoot, and everyone shoots different. The process is pretty easy and only take a few minutes. So don't be intimidated about changing things around. The gun worked flawlessly throughout the season, from 5 degrees blowing snow to 45 degrees in the salt marshes of the pacific coast and not a probem and no rust to boot. Frankly, that's the main reason i bought the gun, because of the aqua finish, and it works!!
I have a 3" Rem 1187 Light Contour and shoot all types of loads through it and i wouldn't say the beretta is that much less of a kick to justify the extra money for the KO option. It sounds good in advertising, but real world shooting, it shoots like a 12 ga. with heavy duck/goose loads in it. But i would definatly buy the EII instead of the EI, since the intoduction of the new ergonomics and aqua finsish it can't be beat, not even by the SBE.
May the skies above you; be blackened with birds
