For what it's worth, I really liked these sticks. I am a case study of 1 and haven't used every high end brand out there so take this for what it's worth.
To me, they are likely the best value to weight/height ratio out there with the included aiders. I'm about 160lbs and noticed minimal flex when stepping on them. They also bite to the tree really well and will stick to the tree on their own when loosening the rope after they are seated. They do have a distinct ting sound when they hit another metal object, but just being careful and moving slow when packing/unpacking has been enough to mitigate that for me. The aider isn't good or bad compared to others i've used, as long as you're careful to get your foot centered then climbing is quite easy.
Overall, these sticks had me almost completely give up 1 sticking this past season. I would pair two of them with my 1 stick w/ 3 step aider (so 3 sticks total, each with 3 step aiders) and can get about 20 ft.
