I have been debating on trying them also , in the past if I'm going to sit and glass , when, I Get close to a good spot I find a sturdy dead limb and carry it and use its from a sitting postition on a steep side hill. but the older I get the more I think about those tripods. The problem for me is , the guys who got me started hunting didn't believe in using even a sling, so I don't use one of those either, my rifle is always in one hand or the other. When I kill a deer or elk I make a sling out of a piece of mule tape, until,Get back to camp.
For me it's how I was taught.
The Primos Triggerstick Tripod is the bomb. It's light, quiet, and fast to deploy. Not expensive - even from Uncle Larry. Get the carry pouch. Worth the few $$. A Breeze!
