I have fitted many of the Graphtech piezo/Hipshot bridges, and I would say if it isn't a fretless I generally find the piezo unhelpful at best and sometimes downright speaker-threatening at worst. Don't bother on a fretted.
I like the sound of a good piezo, but the subharmonic thumps you can generate can be very harmful to speakers. And they sound much 'politer' than magnetic pickups, as they are indeed full range.
In general, if it isn't already installed, I wouldn't spend the money and effort. I'd look for a bass with it already installed.
Sorry to be such a downer, but I have spent plenty of time and money here with some disappointment, even with the very nice Graphtech systems.

Did you use the Acousti-Phonic preamp? I'm curious how it compares to the Fishman Powerchip?
