Hi, My wife and I have the Harris bipod as do many of our friends. I believe Harris is the best but think their model numbers are screwy and confusing. We all have the HB25C S which is the 13 1/2 to 27 swivel, also the most expensive. The swivel is worth it. I don't think any of us are much over 6 foot and my wife is 5'7" and it works for all. Also I must mention that we've made the shooting sticks, seen on this forum, For under ten bucks. We tailered, modified, and adjusted them for our needs and use them almost exclusively now.
