How many beads?

[taltos]

David, what works for me is to use the calculator and then go half as much again. For example, if the calculator said a pound, I would go a pound and a half. This seems to give a nice buffer and bounce back from when I am rooting around in a cooler and have it open for a couple of minutes. Also makes for less frequent misting of beads in the dry winter climate. Hope that this helps.
