@DB4x4 was saying, play with tether height. I lean primarily so I keep my tether at eye level and my bridge short. I also do this because I hunt thick stuff and deer play in peekaboo so I have to be ready to shoot, no time for foolin around. I also keep the leg straps snug but not stupid tight and my belt a bit loose so the saddle will slide down just a bit and provide cuppage. I have widish hope so I run a flex which provides for maximum cuppage but I think that might work for your scenario too. Also what you’re describing is hip pinch. Try what
@DB4x4 suggested. You might have to go up a size if you hunt cold weather. Here’s a pic of me hunting the other day. My tether looks high but it’s actually eye level. Note short bridge. And because reasons the pic is upside down but you get the idea.
