Sorry, I was referring to the Peregrine XP above. The Peregrine XP also have a sharper view to the edges or larger sweet spot. The Peregrine XP was Steiner's pull all the stop's type bino, but it just didn't compete with the mindset "big three" guys if you know what I mean. I've compared the Peregrine XP to Leica HD's, Zeiss FL's, Swaro EL's and SLC HD's and, IMO, there isn't a spit's worth of difference between them optically.
