Re: S&B P4 or P4 Fine
A lot of people like the P4Fine over the P4 because it's clearly not as thick.
I have a P4F in a 3-12X and think it kicks ass, but don't like the P4F in a 5-25X, and prefer the P4 in my scope of that type.
It's pretty much personal preference, but there is a marked difference. The issue is at lower power in a scope like the 5-25X and I know there are images posted online somewhere. The guys from Scandinavia have them for sure online.
I would say it depends on your use, for general shooting, competition like F Class, etc, the P4F is a better choice, for a tactical optic under a variety of conditions, the P4 get my nod -- I think here the P4F is much more desirable if that helps
