Slippery Slope... You ain't Kidding!

Hey guys. First off, greetings. I have been lurking for quite some time. I have been enjoying the hobby for about 2 years now. I just ordered a few sticks and realized that I have no room in my current humidor. So I made an emergency run to Wally World (actually 3 locally. It is hard to find a cooler in Ohio in December.) and Purchased a 28 quart cooler. I took my oasis and put it in there and all of my sticks plus current additions. Waiting on the holidays to conclude to purchase some beads and put them in there. Any ideas on how many beads I will need to purchase and what type?

I have included pics of the old humidor and the new coolidor.
