I managed to scoop up an F1 from the EE this fall.
Super happy with it, fits my needs perfectly. I mounted it on my Tikka lite in 300WSM. I was was comfortable shooting right to the last minute all hunting season. The illumination can be set very low, very little glare on the bottom end and the glass is damn near on par with my NXS. I'm comparing 50mm obj on the SHV to 56mm on my NXS so maybe that gives the bigger scope the edge.
Only complaint anyone could have is the weight but.. we're asking for turrets and illumination here
Edit: you asked about eye relief, I was nervous about it at first but I haven't felt even a light touch on the brow yet. This 300 short has a moderate kick to it (200 grain ELD-X @ 2825fps). I have the scope in a Near Alpha, set back on the rail but centered in the rings and I'm comfortable both prone and off hand. I do have a longer neck though I'd say, maybe that helps me a bit
