I went to specifically check out the 12.5x50s. They were definitely well built, and lighter feeling than I expected. I didn't personally notice that they were higher mag than a standard 12x. And their FOV was pretty solid for a higher mag bino. I definitely didn't feel like I was restricted on FOV which I've found to be kind of subjective. Free handing them didn't seem any harder than the 12x50 Razors. 12x50 ELs on the other hand, wow, best binos I've ever looked through.
I had talked to the Outdoorsmans guys on the phone before about the GPOs and they all told me the same thing, which is that they are "in the same class" as Razors or Conquests or Trinovids. The guys I talk to there seem to believe that they're all close to the same performance and that personal preference mattered more at that price range. I tried to get them to tell me what they thought was best and they wouldn't. I have also asked about Meoptas and every guy I talked to there doesn't like them (is that because they don't carry them? Idk). And one specific guy hates Razors, but only since they moved production to China.
But back to the GPOs. The guys at Outdoorsmans whose job it is to look through optics seemed generally impressed with them, as was I. Binos for me personally in that price range would come more down to ergonomics, and their eyecups felt a little bulky and just didn't fit my face well. Apart from that they're very nice. But like anything south of $1800, I just didn't feel they were on par optically with Swaro SLCs (GPOs marketing claims to be of that quality range). I keep trying to find a pair that are and I just can't. I asked Mark Denham if he would choose any of those 12ishx50s in the $1000-$1500 price range over 10x42 SLCs and he would take the Swaros even though he loves 12x50 binos (him and damn near everyone else at the shop ran the 12x50 ELs this year). Having looked through them all I agree. To tie it back to the original post: if you can afford SLCs or can wait long enough to find a good deal then you should buy them. The HD glass models at least (58210 or 58310).
