I'm sure you'll get much more educated answers than mine, but I do have two points. First, test the gear by hanging something three to (preferably) five times as heavy as your model, then swinging it back and forth for awhile.

Second, there's an 'edit' button on the lower right of each of your posts, which disappears after 24 hours. When you have an afterthought within a day, instead of quoting your original post and adding a line, just hit the 'edit' button and follow the directions.
