Ditto on the Seat of the pants harness. It'll cost you about $70.00 but well worth it.

The reason I think they are better is because of their design. They not only distribute the shock & body weight across your upper torso but also your legs. They also use what is called a high tether attachment system which means the attachment point is high on the harness which helps in not restricting your movement or interfereing with drawing your bow. Also the system they use for attaching yourself to the tree is fully adjustable so you can set how far you can lean out from the tree. One last thing is that they come with a fanny pack that the whole thing folds up into, just clip the belt around your waist and pull it out and put it on just like a jacket. If you've ever fumbled with one of the other ones in the dark, you'll know what I'm talking about.
