I use both sticks and bipod. The bipod is for longer shots that require prone shooting to be solid. The sticks are for the closer shots.
I prefer a pair of sticks instead of the monopod just because feel I have more freedom to us my mouth calls and switch back and forth to between howler and calls.
I tried a pair of shooting sticks with screws in the bases and found a number of places where they gave me fits. It was usually on ground that was frozen or rocky. I cut the screws to have sharp points to stick in the ground and found that those were not that dependable either in the areas I hunt. The sticks were noisier when trying to move for a shot when necessary. I think dowels are better, especially if coated, but I would likely put rubber feet on them.
Also, a lot of my calling is from higher ground, overlooking draws and valleys for better visibility of animals coming in. If the ground below me was too steep, I had to move to a spot that I didn't like as well because my sticks would not adjust to the extent I wanted.
I finally broke down and got some Stoney Point adjustable shooting sticks. Nothing is perfect, but I prefer the sticks I bought.
