I was a busy bee last night. Not only did I finally tame my Ithaka, I found the perfect (for me) configuration for my Spheroids.
The only Ekowool hat I like in these is the 2mm. I've found the 2mm is the best Ekowool in multiple devices - Spheroid, Diver, Ithaka, eBDP. It is not too thick to be usable, like the 3mm, and gives tons more vapor and flavor than the smaller varieties. One man's experience, of course.
Two strands of 2mm Ekowool, 32g A-1 Kanthal running at 1.4-1.5 ohms, large gaps between the coil loops, wicks trimmed down a bit more than I had them before (I think I had them a bit too long, they were impeding airflow a bit).
One of my top juices is Mewlew's Magic Blend from VCV, and I am very familiar with it in many devices. The Spheroid in this configuration really brings out an intense chocolate flavor that is very muted otherwise.
I am becoming more convinced as I find my sweet spot with all these devices that I will end up marrying specific devices to specific juices and configurations. With every one of my favorite juices, it seems like one device in one configuration blows away all other devices and configurations.
I'm very glad I have picked up 2 Spheroids, because 2 of my top 5 juices vape best in them with the above-noted configuration.
I might mess around with other wick materials in the future, but I have been in tinkering overdrive for many weeks, and I wouldn't mind slowing down and enjoying some vaping for a while, now that I've optimized most of this gear for my use.
