I've heard the Merlin has a somewhat restricted airflow. I like my Serpents with the air flow wide open. How does the Merlin compare to that?
I've seriously decided that these Serpents have passed the iSub G tanks as my favorite everyday tank. I was thinking about getting a couple more of them, however, I've been hearing a lot of good things about the Merlin as well. The only reason I've hesitated on that one is because of the restricted airflow. I'd appreciate hearing your thoughts on how the Serpent and Merlin compare, airflow-wise.
