I've had a few but the best by far are my Lone Wolf stands.
Aside from being very quiet, these 3 weigh per each: 14, 14 & 17lbs.
I cable lock my two fixed stands to preselected trees and have the Assault Climber II for portability.
the separate 4 LW climbing sticks for the fixed stands weigh a total of 6lbs. but these go in/out with me while the fixed stands remain.
