I like the Impact cosmic head, Its on a Toxonics slider sight, something I put together and really like. Ive shot single pin for years, and now I cant hardly shoot a multiple pin sight. I have mine marked from 20/30/40/50, and usually leave it about 25 yards while Im in the treestand, if the yardage is more than 5 yards different then that, its just a simple thumb push. I love it.
