Drifless,
I used the E1 for two seasons and two bull moose. A very tough scope but a coupla issues:
The reticle was very "busy" and not as bold and legible as the ballistic plex.
The excessively large tactical turret caps bit into my wrist when I carried at the balance point.
Still a great scope.
But for these reasons, I prefer the fullfield 2.
