Have several sets of the doubles, all I use. Awesome product, very sturdy and stick hard to tree.
These are great when wearing larger winter boots or for people who may need to feel a bit more comfortable climbing. Great footing and stability
These are the primary sticks I use. I typically have most of my sets hung before deer season so the extra weight of these aren't an issue. This allows a safe climb up and down and once they bite in they aren't moving. I recommend these sticks for the private land hunter that leaves his stand and sticks out there all season long.
