p0k,
Technically, I shouldn't be talking to you - you ended up buying the two basses that have given me the most GAS this past year (that Fender AND that sweet Spector of yours)!!!
When you bought the Fender, didn't it have TI flats on there? Were you not feeling the tone from those? IMO, flats + nice, passive bass = yummy. As I said though, IMO...
If you're looking for a bit more brighhtness (rounds), I'd suggest going with some from of Nickel string. XL's or DR Lo-Riders, perhaps...
I'd say it depends on your playing style, mainly.
Good luck! And enjoy those basses...
