I have em all, the mono pod and the sinperstyx and the Harris Bipods. My 223 and 204 and 6.5 all have the Harris 25s on them and I find them perfect for me. Yeah they are heavier, yeah they are always on the gun, yeah they can be not ideal in every landscape and terrain and setup. But I like them. Plus, I am a little guy so my 25s can get to almost any height I need them. Remember, you dont HAVE TO use the full extension of both sections to use the Bipod. I often and I mean OFTEN adjust the main section mast to the height I want by just snugging up the tensioner lug and then it stays just fine. Then, I have the exact height I want based on where I am. Works for me.
Styx may be more flexible for some and that is fine. Plus, as often as I carry a ladder, last thing I want is something else to carry!!!
Try what you can and make a decision that suits you. One size does NOT fit all!
