If you prefer the Bartolini sound over the Alembic sound, go for it.
IIRC, the standard Persuader package has a fixed 8 dB Q boost on the filter, and there is no switch to turn it off. For my taste, the 8 dB boost is really too much, and so I had the 0/8 dB Q switch on my Spoiler replaced with a 0/3/6 dB one. Much nicer on the ears, especially with new strings. Check with Mica if you could add such a switch yourself.
Whatever you do, keep the original electronics, and try not to drill any additional holes in the bass - well, except if you add the Q switch, which is an excellent upgrade on the original package anyway.
