TaffyClay, you’ve got a really nice scope already, so sure why not get a “lifer” binocular? I might suggest the 8.5 SV instead of the 10x, or second the 8x32 SV as suggested by Lee, but that’s mostly because I’ve never been a big fan of 10x. Lots of good stuff to choose from these days so look at Zeiss SF and Leica Noctovid as well.
In any case, and depending upon context, a good scope just kicks the butt of a bino so don’t worry about that.
I don’t consider a scope a “luxury.” Nor do I think binos and scopes serve “very different purposes.” They don’t do the same thing, of course, but it’s all called “birding” so in my book they generally go together. I could easily provide a dozen examples from the past month alone in which a scope either yielded a hugely improved view, or made all the difference period. It depends on context of course, but in the winter I’m often looking over distance and water, so there you go: get a scope. First example. A Eurasian Wigeon is not exactly a mega-rarity here in North America, but I am sure I wouldn’t have found it among a bunch of distant Americans a couple weeks ago without a scope. And I was also using the 8x32 SV at the time which would have been almost useless at that distance. A little Nikon ED 50, 27x kicked the Swaro to the curb in that case. Or—example two—a group of four birders discussing Tundra v. Trumpeter Swans. They really wanted Trumpeter, digging into their books, scratching their heads. “Look through the scope,” I said (Meopta 82mm this time). “And viola!! All Tundra.”
LOL. OK, slight exaggeration. They still had some trouble, but at least I could point out the differences (head shape, bill shape, NOT so much the yellow lores or lack thereof, etc.) that a pair of binos would leave you confused over until you really had the ID down. I could go on with examples, but I think the OP knows all this.
Often a scope, as with really good photography, is more about appreciating the aesthetic beauty of birds anyway. I think that’s about half of it. For me anyway.
So sure, get a nice pair of binos. You’ll use the heck out of them! Keep the scope of course. You’ll use that too.
