Go with the Jake fan and short beard, unless you know you're hunting a dominant bird. I've had Jake's, and even sub-dominant mature birds decide they wanted nothing to do with my B-Mobile when set up with full fan and beard.
The full set up, though, will really upset a boss bird. I've had some good shows from them since I got the B-Mobile, and they're not paying attention to anything else at all. Lot's of fun.
