NO. I use Swarovski 8x56 around my neck. They are the same size and weight as the 15's but the advantage of the 8x56 is that I can glass while it's still dark, they can't be beat for glassing in low light (7 mm exit pupil) and we all know that's when biggame is making their move to their beds.
I carry them with a bino harness and when I stop for a quick look, I rest them on top of a mono-pod / trekking pole.
YES. When I stop to do some serious glassing, I mount them on a manfrotto bogen tripod, or a cheaper lightweight tripod if I'm backpacking in. I glass for game with these 8's but when I spot something that deserves a closer look, I attach the doubler and now I'm looking through a 16x56. I've looked through 15's set up next to my 16 and it is the same. A note about the doubler; Don't bother to buy one for anything other than an 8x56 because they will be too dark. Example; attached to a 10x42 you will have a 20x42 with an exit pupil of 2.1 mm but with a an 8x56 = 16x56 you get an exit pupil of 3.5 mm and that's almost the same as the 15x56 that has an exit pupil of 3.7 mm.
