I know you've decided but I have my hdb's in FHF gear.
I used them on two elk hunts and it's a nice comfortable system. I really like the kuiu as well but the lack of range finder option pushed me to the fhf.

hmm I had both . . .. upgraded to the new one and used them side by side. I like the ergonomics better, bit sleeker design and the optics were better.
I sold the old one on ebay for around $800 . . . . . eventually I'm going all in on the swaro STS in 85 but i can buy three of these vortex for...
I have always carried swaro bino's but for a recent hunt i picked up the leica hd-b. Man they are super nice glass, great quality and very accurate readings.
