Cabinet Humidor Questions

[paris1129]

I recently purchased a montegue cabinet humi from tampa humidor. It is a really nice piece! I want to do this right so I can take care of all my stogies, so I have a couple of questions for the more experienced individuals with this sort of thing:

1) I purchased 70% beads to use in addition to a cigar oasis XL plus. Should I be aiming for 70% in a storage cabinet, or lower like 65,53 for which most on here seem to indicate a preference? I haven't used the beads yet, so I could still exchange them or just go buy 65% beads.

2) I am having to refill my cigar oasis every 10-14 days it seems. I know it is winter, but is this normal? I thought these should last a few months in between refills? I left it in the empty cabinet for about 2 weeks before the levels hit 69-70% steadily before I starting storing cigars in it. I hear it run about every couple of minutes for around 15-20 seconds at a time. Seems a lot to me.

3) Because I am refilling the cigar oasis so often, I am considering the use of the beads I bought, which I haven't done anything with yet. What is the best method for placing beads in a cabinet humi? Bottom shelf, middle, top? I have seen some pictures of others' humidors that have the beads in little sock like sleeves. What are these and is this better than placing them in a dish?
