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.
