I've got the 5500 model, and it's got the adjustable hood, to adjust pin brightness, and it's the cat's meow. Don't remember if they all come with the brightness adjuster or not, and don't remember how long the fiber is, BUT I have to adjust to dim when in full daylight and about the only time I adjust to full brightness is when in a DB blind.
I've got the same sight. It's the OL 5500 and it's got 5 feet of fiber optic on it with the rheostat. It is a GREAT sight!
