I also have the same saddle and experience the hip pinch that you're speaking of, even with adjusting the tether length and trying to position the saddle lower on my butt. What I now do is carry in a sit drag as well and use that in addition to the saddle once I get up to hunting height. With the sit drag I position it much lower on my butt then I can with a saddle. When I try to position the saddle lower it does not come up my butt very well in acts as if I'm sitting on one piece of it still causing the hip pinch. Would the sit drag when I sit in it at a lower position the entire surface area of the sit drag cups my butt not causing any pressure points and this has relieved the hip pinch for me.
