I am using my first cisco 306 with xl drip tip and avidvaper drip shield. I like the setup. However, I am really not impressed with performance. The vapor is huge. I am a diehard boge 2.0lr carto guy. I use them in my tanks and the reo. I noticed with my 306lr that the TH is just not there compared to the carto. Also, more disappointingly, the taste is vague and barely recognizable. I have read so much about how the 306 really brings out the flavor and effect of the juices one uses. But it doesn't seem to stack up to my cartos. With my boges, I get tons of flavor and a good kick with the TH. Anyone else have this experience? I have only used 1 so far so maybe it's a dud? I am reluctant to assume this, though, because it is working fine as far as I can tell. Just getting low performance from it. Also, I am in the learning curve, as I have already had 3 bad dry burns. I am used to the cartos lasting forever between squonks lol. I still have a few i06s that I havent tried yet, might give 1 a go later.
Then I must be the exact opposite of you, because every time I try cartos, I get disappointed with the flavor and go back to the cisco 306. There is definitely a bit of a learning curve to using them. It takes some time to learn when exactly it is time to drip or squonk. You eventually learn to tell when it's starting to run dry and add more juice as needed.
