I know your asking about els but If you can get out and spend a couple days with the pures I would do it...yes they cost 1k more...yes at 1st glimpse in the store they are marginally better
But in the field...they are kings...my 10 pures outperformed my b518s at distance..and often when going from the 10s to the 25x stx it's amazing how little difference there is some how...idk how to even explain it...obviously that sounds crazy but it's just my thoughts...if the pures or els get you back to work one or two days sooner they pay for themselves in short order...depending on how much you hunt that could add up fast
Just some thoughts
