Here is the best advice you can provide (strings--- I'm happy with my Roto 77s; might slap on some 88s):
1. Buy the bass and buy the other pick-ups...
2. Play bass as is; record it in several different situations to provide a good "listen".
3. Remove stock; install Vpups.
4. Repeat step 2.
5. Critical assess the pups
6. a. keep the vpups in; play. Or...
b. uninstall vpups; install stock; play.
By saying "choose what you like", this is the extant you would have to go to to make a determination, following this advice.
This would be a very solid method, but one that is extremely time consuming.
It is very easy to A/B amps, guitars, etc. You just go into your nearest retailer and play what you want. You cant A/B pups, strings, etc in stores, making the "whatever sounds best to you" argument (yes, it IS the bottom line) really not practical.
If you can't compare the 2 pups, fine. If you can't say which, in your view, someone else should go with- fine. It really DOESN'T matter. BUT... searching threads, trying to gather useful information/opinions regarding gear, would be a MUCH smoother ride without the 4 posts per page asking posters to try it themselves (and, yes, this does underline the importance of *MY* opinion---but in some circumstances it just isn't logical).
The Golden Years
I cannot see, I cannot pee, I cannot chew, I cannot screw
Oh My God What can I do
My memory shrinks, My hearing stinks, No sense of smell, I look like hell!, My mood is bad - can you tell?
My body's drooping, Have trouble pooping, The Golden Years has come at last
The Golden Years can kiss my ass.
