Weird. Where I live, Loomis uses their own wrappers and are I've had terrible luck with them. The bank that I usually by boxes from uses NF String wrappers and I've had pretty good luck.
Once my bank changed carriers my luck DRAMATICALLY increased. I usually get $4K a week, this week is basically a skunk, but on my best week I got 98 halves with about 40 of them being 90% A typical week produces 20-30 40%ers and a dozen90%ers. Loving life these days, skunk weeks are kind of like a break
