I've used a lot of climbers over the years, Summit included. Remember th old Baker stands? Some can make more noise than others, but there are ways of reducing it. Filling aluminum tubing with Great Stuff foam is one way. Another is, especially with the Summits, to grind down the teeth about 1/8" and round off the corners as they do dig into the tree quite well. Especially soft bark trees.

For the most part I've learned that there are not very many stands that are really noisy. Just people who make them noisy. I see all the time people saying that they can reach 20' with such and such stand in a matter of 5 minutes. All I can think is that in doing so every critter within a half mile knows they are there.

Learn what makes noise with a certain stand and do what you can to dampen it. Then when in the woods take your time and be quiet both installing it on the tree and climbing. What's the difference whether it takes another 10 minutes or so? You're most likely going to be there for hours anyway. This just one other matter where learning to be stealthy is part of the hunt.
