For Predator hunting, I love my Vortex Diamondback bino's 8X, because they are $200 smaller and light weight. They take a beating and are really clear. I got the 8 powers because I can spot coyotes at 1000yrds with them and that is good enough. I always scan the brush within 300 yrds really close before standing up for coyotes and especially bobcats. 8's are great for this.
Shooting I prefer shooting sticks because I can move them in closer to the magazine, to allow for greater panning without moving them.
I don't do the vest, becuase I have a pack and a seat. The turkey seat i have has a back rest, and that to me is important. after a day of calling that back rest makes all the difference, especially if you are going to call 2 days in a row. The best part is that it holds me up 4" off the ground. You wouldnt' think it makes a difference, but it does.
