I have been using sticks exclusively for about 4 years now. I used to be a 100% climber guy and just haven't carried one much in recent years.
When I first started, I made a decent amount of noise with my sticks. Now, I honestly believe I can make it up the tree with zero metal to metal contact IF I take the time to pay attention and do it right.
I have two pieces of advice for you.
1) Test out a few systems to see which one you like.
For me, I can't seem to beat the benefit of a climbing stick. Finding the right length, number of steps, and aider or not is on you. Once you find that system.
2) Perfect it!
Find the times you're most likely going to make noise and then plan for those. My most likely times to make noise are when I am taking my sticks apart or when ascending with the predator messenger style(it works, but I'm trying to work it out a little better). On the way down, I typically don't care as much about the noise and will drop my sticks from the tree, so noise isn't that big of an issue.
