Frankie, I am of the opinion that anything you can do with a climber you can do with a strap on. I can go up and down any tree nearly as quickly, probably quieter, and can change trees no problem. I can also use nearly any tree around, even those with limbs in the way.
Don't count them out only for the reason you gave.
I use the Chippewa stands. They use a separate hanger that makes things quicker, easier and quieter. They are also very stable and quiet.
Of course, a good ghillie and seat can work wonders as well.
