Lots of good info here. I would agree that the Harris 25" swivel model is the best choice if a sitting shot is desired, however, as most have stated, it just too high for most prone shots. For these occasions, I do what someone else mentioned, I just use my pack, a rolled up jacket, or anything that will get the forend five or six inches off of the ground. A lot depends the terrain where your hunt. I have very few opportunites for prone shots, so the Harris 25 is what I use when I want an attached bipod. I recent years I have moved more to the shooting sticks for deer and hog hunting. The model I use extends from about 25 inches for a sitting shot, to a full 60 plus inches for standing shots. While not as stabil as the attached Harris bipod, I can easily get a good enough rest for 200 to 300 yard shots at deer sized game. If the target is smaller than deer, then I would opt for the more cumbersome Harris. I usually strap the sticks to the outside of my pack for quick access and don't usually go out into the field without them. I even use them in box blinds to rest the heel of the butstock for a super stabil rest. This allows maximum stability for the longest of shots in the field.
