You are already sacrificing valuable cigar space with a ton of beads. I use a pound of HF beads in two bags in both of my 28btl Vinotemp's. No Rh issues in the past 3 years. Rh is always going to drop when you open the door, you could add 20lbs of beads and this will still happen. It really sounds like you have a bead storage cooler with very little room left for cigars.
