I have both the strap on ladder sections AND the ladder that connects together. I use the screw-in steps 99% of the time.

The ladders are too heavy, noisy and cumbersome for me and I now use them in set locations and leave them there the entire season. My screw-in steps are always with me and get me into nearly any tree I want and they fit nicely in a small pack I have attached to my fanny pack. It's convenient and quiet for me.
