I recently purchased some RY4 cartomizers from Steve, and am not getting very much vapor out of them. First few puffs are ZERO vapor. From there it improves to the point of break in puffs of other flavors and gets no better untill the "burnt" taste kicks in. They taste good, but no vapor/throat hit is a problem. They also didn't seem to last very long. Maybe that's in my head though. I was puffin pretty steady trying to make them work. I'm using auto batts from, dare I say, CigEasy. One of the carts was definately my fault due to baking it during break in. I've refilled a couple of them with different juice and vapor improves. I guess my question is "is the RY4 normally short on vapor, or am I screwin somethin up?" They were 24 mg carts, in case it matters. I really hope it's me kuz I think this is THE flavor I'm looking for. Thanx in advance.
