Foam or no foam?

[Whatigot]

jeez...
I'm in the middle of setting up a 95 that is flat glass with no trim on the bottom.
The glass sits flush on the stand (which is custom made out of very good wood and flat/even as can be).

what should I do?

Right now, as the guy who had it before me had 100 lbs of LR on it with no issues for 6 years, I don't hink I'm going to use foam.

But if anyone here can save me from myself, please do so.
