PWR,
I have the same setup as eyedoktr, and I agree with him. The 9 degree is nice to clear up some of the clutter when fishing in shallow weeds, its nice to limit the dead zone when fishing a sharp dropoff, and it is a must when you get up around the 40 foot range.
As for power to pick up small jigs... the 9 degree will pick them up a bit better, but it is not as much as if you switch between hi/low power modes (if you are using a FL-18).
