Well, I got my stuff in a few minutes ago. I set up the Cinis with ekowool (thin SS core, just enough to go through the deck). Awesome. Next, I set up a new RichMan genny and put it on the DX490 (my AC9 is on my paps at the moment, I'll probably replace the RichMan on this device with another AC9 or a Kayfun and put the RichMan on something that matches the finish better). Awesome. Last, I juiced up the 650CT. Yowza! I quit using cartos about a year ago because I just didn't like them. I got much better flavor from RBAs and didn't find any tanks I liked. I was a little skeptical when Zen started talking about doing a carto tank, but I figured if anyone can make them great, he can. So I rolled the dice and figured I'd try one out. I am LOVING this thing! I don't know what kind of magic he worked, but man, oh man... Flavor is fantastic, look and feel are perfect, easy setup. If this isn't a fluke and it stays this good, I see myself picking up a few more of them and giving away my twists and evods/protanks. (I travel a lot and gennies aren't very travel friendly).
I did also order a kick to try on the CT. It doesn't necessarily need it with a 2 ohm boge, but it is very nice to have. I get a small gap though at the switch or burner end, evidently my kick is a little tall. I split the gap between the top and bottom and now you'd have to be looking for it to really notice it.
I'm a very happy camper. My first three Zen devices certainly didn't disappoint - worth every penny.
