more VG-99 questions

[Douglas Baldwin <coyotelk@optonline.net>]

Recent talk about the VG-99, and a financially successful yard sale this
past weekend, has me jonesin' to own one.
    How's the GK-3 pickup? Should I consider a dedicated hex-output guitar,
like a Godin, ferinstance? Should I consider the GKKITG3 on-board system?
I'm excellent with tools and guitar electronics, and I can play very
accurately.
    And how's the MIDI tracking in a live context? I dig that folks say 
they
can send MIDI to their 'puters for future use, but how's it track in real
time?
    And, bummer of bummers, it seems that *some* effects are polyphonic,
while others are not. Like the Slow Gear is polyphonic (yay!) but the Ring
Mod is not (boo!)? Might someone bother to list *what* is/isn't polyphonic?
    Where else might I go to get the big picture on this piece of gear?
(I've read a few reviews, and checked the Roland site, including scanning a
bit of the manual.) I'm deep into the GT series of pedals, by the way.
Thanks loads in advance,
