Scott,
Did you ever try to take it to a finer grit than the stock 600 grit?
Visionary does/did say it was a particle pearl; it was just released with a dull cover, much like the Roto-Grip RS-P, which is 800 grit.
I always thought about trying one, but all the negative reviews dissuaded me.
Today, I'd try to modify the surface tp 1000 grit compunded or 2000 or 4000 grit. I'd bet it would be wonderful, given Visionary's really good cores.
(Side Note: as time goes by, does Visionary's match-ups of coverstocks with cores seem better and better to anyone else? I wish they'd name their coverstocks so we could track how they worked with each core with which it's used. I wish, I wish ...)
