Add another vote for the FF II. After missing two turkeys with these tight TSS patterns I went with my first sight on a shotgun, FF II. I won't ever hunt turkey witout one again. 7 turkeys fell to my FF II and TSS this year in 3 states.
I found it very easy to dial in. Like the other poster, I used dove loads at 15 yards to get it close then check it at 50 yards with my TSS.
