They look like a very good set of sticks. I am sure they will work real well. When I use the sticks, I like to get my back to a tree and have them infront of me. With my back rested, and the rifle's weight on the sticks only, I can get very steady, and actually adjust the angle of the sticks to raise and lower the elevation of the rifle aim a little. Those like like they will work great.
When I get to my stand I adjust the height I need by moving the wing nut and bolt to a different hole. I then lay my glove in the V of the stick and shoot out of that.
