The Q is their best and newest, and yes, a bag vape will help with your coughing problem for two reasons. One is that the vapor gets a chance to cool as it enters the bag, and two, is that with bag vapes, you have a higher air to vapor ratio. You just have to make sure not to turn up the heat to high.

btw, since my last post, Zephyr sent me an Ion for evaluation. Great bag vape at almost half the cost of a Volcano.
