Definetely FFP, I find it more versatile.
I'm sticking with "P4 fine" because P4 alone is just as thick as the P1. When shooting shotgun casings at 200yds, I can just make out either side of the casing because it's so covered up by the reticule. The point being that I'll likely never need the 4X setting, so SFP would not be worth it just to be able to see the reticule.
