There is not a whole lot you can do to a 3-element yagi. I've modeled the 
factory design of this antenna and tried to improve on it using YO, but as
has 
been said, it represents a pretty good compromise of the various factors out
of 
the box. So I agree with Carl here. I wouldn't be inclined to mess with it.
Any 
small improvement you might make wouldn't be worth the trouble.

Having said that, you have to believe that this state of optimization is
blind 
luck, since all the other Cushcraft 6m yagis can be significantly improved
using 
computer-aided modeling and redesign.
