I swore I would never,,but I got a set of Tony at Kelso and gave them a try earlier this spring. I've had them out with me on every outing since! LOL...
I've ditched the tie bands, so I'm now in a position to deploy them in very swift time and get ready for a shot. Ok, I have lost a few opportunities at very close ranges where I had to be super-swift and where twin sticks would potentially have landed me a shot, but I have instead been able to take bucks at ranges where twin sticks would never have allowed, and comfortably take a shot on a deer that just stops for that second between young trees at 100-150yds where I'm not able to be prone.
the jury's out, but I think I'm sold, and I have to admit, my 'standing' shot placement has improved off the sticks too...the only negative thing is the damn noise they can make if you're not careful, and the time it takes to set up a shot if you need to be in a rush...you win some, you lose some,,but overall, I think I will win more than I lose with them.
