I did some mods to my LW Assault hang on.
1) Third Hand bow holder on the seat
2) Silenced by wrapping with Stealth Strips on the post, cables, and wrapping 5/16 rope around the front edge of the platform.
3) Added stick talons to hold the sticks. No more bungees.
4) Swapped the strap and buckles on some sticks with 8mm accessory cord. Added stirrup extensions from 1" tubular webbing.
5) Tossed the harness and modded a rock harness with a linemans belt and tree tether. No limit on height now.
So the setup I carry into the woods now is under 15 pounds total (typically bring two sticks), silent, and can climb any height into the nastiest of trees safely.
