bead question

I don't have any problems with the HF beads. I just thought about adding more beads to help the temp swings when the unit turns on or the door is opened. Since I was looking into getting more, I just thought about trying the other beads since they seem to be so popular.

I don't really have any maintenance with my HF beads. I have about a pound in the bottom and a pound in the top. I have a few small tubes spread about the shelves. I have not sprayed them since they were placed into the unit almost a year ago. The EdgeStar stays around 65% unless the unit is running then it will drop to high 50's until it recovers. Every once in a while I will place a shot glass of distilled water inside the unit for the beads to absorb if it seems to be a little low on RH.
