brcfo,
I understand what you are possibly getting at with my tripod head but I assure you thats not the case. My pack tripod is a Surui T-025X carbon fiber with a Outdoorsman Jim White Fluid Panhead 2.0 , Its made for hunting/glassing with spotters and bingo's and I also use their bino mount.

My second tripod is a 2-Vets carbon fiber with a pan head and a FIESOL VH-60 Fluid video Head

Its just a weight/mass issue, obviously the lighter something is the more it is influenced by outside forces. Just rolling the focus wheel causes a little movement and makes it harder to focus quickly, it takes several tries with removing your finger before you get it focused crisply. Don't get me wrong the KOWA 55mm Promiser has some phenomenal glass its just a little difficult to use and the Kowa 66 series just does it better and is still a very packable spotter. There is a reason why most guides carry nothing smaller than an 80mm even though they are a beast to pack. I assure you I have spent many 1000's of hours over the years in a spotting scope glassing for game and many more hours glassing through bingo's on a tripod. I also put on average 12 hrs a month behind a spotter shooting and scoring twice a month in F-class matches.
Believe me I sure wanted to love both the Vortex Razor 11-33x50 and the KOWA 55mm spotters, they are so small and cute and fit in a pack like nothing is there but in the end they just didn't do what I need them too in the end. Good luck with your search and let us know what you decide to buy.
