I have the Gorilla climbing sticks they are light 9lb for the 3 piece.
They are easy to put up and take down.The foot pegs can be swung to either side of the sticks.
Each is 4 foot long and if spaced you can get up to 16 ft up the tree.
They do have optional pieces you can buy.
I just strap them to my stand to carry in and out.
