I just lay the SteadyEddy next to my Stealth NXT. The “clip” that is mounted under the trigger area of the stock does mean that the xb sits higher than without it, but I’m still able to close the semi-ridged TP case.
I love the SteadyEddy for Shooting from a seat on the ground (rx. In a blind) or treestand that doesn’t have a rail, or for the rare (for me) standing shot.
I always leave mine attached BUT, got rid of that clip. It works but, TO ME, it get in the way too often. I just use one of those rubberized twisty "thingies". This way it runs off to the side of the bow, NOT directly under it and this saves some space. Works great, I think. I'll try to find a picture.
