I have the Glider high output S. While I love the sound, there may be a better matchup for the Classic; since I already had the Glider, I didn't do any research. I believe VPI recommends a Dynavector that they'll mount for you at a decent price.
As far as arm mass, I was told it was 12.3g.
Regarding using a maple board under the Classic, I wanted a dust cover to protect the TT and arm; so, I bought a Ginko table top dust cover from Galen (and love it). Hoever, keep in mind that you'll probably need extra headroom with the table top dust cover if your board's dimensions are smaller than the Ginko's (to accommodate the heighth of the board).
