You did arrive exactly when we needed you - ie when we are needing  
feedback on style usability. So in that sense we both lucked out.

Not sure I understand the difference?

Yeah okay. You are doing conditional logic in java code; which is fine  
- however if "fiability" was an attribute in your feature we would  
rather you set up a series of "Rules" one for each case; each with its  
on Symboliser.

I had a little trouble reading through your code (so I may of not  
understood what you were doing very well).
