...a box of KGD. I'm using it now to drip all these new juices I got in my Reo, mostly because it's really easier to wick than cotton or CC (can't beat that when you're rewicking every 5 minutes to change flavors lol).
Another advantage of CCr. It doesn't "hold on" to flavors the way cotton does. So no need to re-wick; your old flavor should be gone in a couple puffs.
