Debridge your 306 atomizers IMMEDIATELY! Makes the flavor stand out a whole lot more, I imagine they're easier to clean this way, but the big improvement here is the air flow, it loosens it up just a bit, not too much, but just right. Time for an RY4 binge

If I was good at linking, I'd throw a vid about it up here, but search on Youtube, there's quite a few DB'ing videos.
Edit: If anyone on here hasn't tried a 306, do yourself a favor, spend the 5 bucks to try it, you get a comfy plastic drip tip included, and you can't find a deal like that anywhere else that I know of. You'll be spending about $6 just for the atty and between $3 and $4 just for the drip tip.
