That rolling ball can suck. Sorry to hear that.
I recently bought a 10x42 Nikon HG, and although they don't have quite as flat of a field as the EL I got dizzy the first few times I put them to my eyeballs. I got used to them pretty quick but it was weird since the EL have never bothered me. Everyone's eyes and brain are different obviously.
Two thoughts regarding 15x:
1) Two miles with 15x is an awful long distance, in my opinion.
2) Some 15x big eyes are dang near as heavy as a spotting scope
