I know this is an old thread, however, I just found this weatherby nation site in February 2017. There is a lot of good information so I just started checking out the various topics.
I use shooting sticks that are shock corded and are good for kneeling and sitting positions. They are 10" folded and about 30"fully extended. I keep them on the side of my pack and are easy to get to. I also use a telescoping walking stick with a rubber cap on the bottom. I have a rubber V on the top that I can use if I am standing. I use the walking stick all the time. It's a 3rd leg that i use for balance whenever and wherever I am hunting.
I hunt in the swamps and hardwoods of Michigan, the mountains of Wyoming and New Mexico, the sagebrush flats and deserts out west. If I am walking and stop to glass for game, those shooting sticks come in handy. I also use them to rest my binoculars for a steady view. If I happen to jump a deer while I am walking, the walking stick allows me to shoot quickly with a steadying rest offhand.
I started using the walking stick about 30 years ago in the Wyoming mountains. After a week of hunting my knees were shot. I realized that walking downhill hurt the most so I would use the stick to ease my way down and sidehilling the mountains. It made a remarkable difference!
I don't use a Harris type bipod for hunting. I think they are too noisy for my liking. My brother has them on all his rifles from varmits and predators to mule deer, clues whitetail, sheep, goats and elk, he loves them. He is the best hunter I know and has taken far more game than I. The only time he doesn't use them is when he is stand hunting in a Shack in Michigan.
Everybody has a system that works for them. My system may not be the best. It is the system that works for me. I think you should try a variety of systems and figure out what you are most comfortable with. We hunters spend so much money and time as we can to enjoy what we love to do. The small amount we would spend on a steady rest system is worth experimenting with to make our time afield successful.
