Hold Down Help - Tile Gaskets w/ Vacuum Table?

I'm desperately seeking the Holy Grail of hold downs. I do a lot of parts which are profile cuts and each one is a crap shoot if it has to be very accurate. The CNC that I have has is a MultiCam44# that the prior owner added an industrial Vacuum Table to. The vacuum isn't sufficient to hold down the wood/plywood w/o additional fasteners of some sort. I'm wondering if Tile Gaskets really work as well as advertised. Having said that I then wonder if a DIY version would be available using neoprene adhesive backed sheet or roll gasket and have a pattern of drill holes 1/8" deep to DIY? Tabs don't seem to work great, etc. Very Frustrated. I'd like to use Vcarve Pro 12 to make some boxes but I can't be sure they won't break loose and lose the integrity of the parts/box.
