I have my pins on hardwood and have tried just about everything listed here. I didn't like the rubbery feet as the pin wouldn't move at all when nudging and felt unnatural, and in general prefer the glides and felt glides because of ease of moving the games for maintenance, though they tend to move a bit too easily when nudging and you have to adjust your style of play.
But recently when I purchased a couple more pins than I immediately had extra sets of glides for, I resorted to beer mats (chipboard coasters from your local bar). Work like a charm, slightly less slide-prone as the glides and best of all they're FREE. Might look a little tacky but I like the play better than the other options.
