I've dabbled a little bit with the fixed Super Chickens. Had a 20x, and now own a 6x and 10x both with MQ. Round counts are low on the 6x and 10x though. Recently sold a 3-15x42 to a bud at work.
The 3-15x doesn't tunnel, but the eye relief changes. Overall a nice scope BUT that SF is not something that makes me warm and fuzzy for anything other than a plinker. Its not like a turret cap... the guts of the scope are beneath that cap. I'm not saying that SS is any worse than another brand, but I'd rather have the rear-focus.
That said, when it was time to buy a variable I was directed towards the 3-15x over the 3-9x. Even so I plan to try a 3-9x sooner or later.
