Personally I love the Petri for flavor! Easy to build and perfect airflow it and my aelus v2 are tied for adv drippers on my vapirsharkdna200.-both are ideal for temp control builds . The way the post locks down on wire gives it an ideal strong connection. They are both great flavor producers and make a healthy dense cloud. But are more along the line of flavor atty.
if you like a looser airflow though, its worth getting the dotcap. (chuff)
I had reservations pulling the trigger myself. Then when I got it and saw the workmanship and the flavor and ease of build makes it all worth it
customer support is lagniappe but equally impressive.
