The only new technology in hang ons iswith straps that can be hung 1st like the new millenium and the summit copperhead. These and the Lone wolf are all in the 12.5 # range. What is there to improve on? They work great and I never sit in my stands and wish they had any better this or that. I like the way my lone wolf alpha can adjust for crooked trees and the seat leveling feature is also nice. When you get into lighter materials than alluminum the cost is going to go WAY up. I think that my 12.5# stands with my climbing sticks mounted to them are still fine in the weight dept.
