I like duals on my Origen dripper but single is fine on Prometey2 (don't think anyone duals a P2) but I may be with you on the Achilles.
I just single coiled a Immortalizer with the wide diameter and even dual air holes, with a 0.40 ohms single coil its awesome.
i think the large chamber really gets the vape cool enough for my taste and am sure the Achilles, like the P2 will be my cup of tea.
I can understand "events" and will be patient
heck i have a lot to vape on, and the Achilles will elbow its way up to the front when it gets here
strange though, I'm sure i was early signing up on the last pre sale
its been a loonnng time.
