Serenity Gear provari regular length sleeve works well on the orion. There is a round hole on the other side of the sleeve as well.

Trust me when i say this. You do NOT need anything but a 3.7v battery if you roll the right coil on the right wick. Use 500 mesh and use a 6/7 wrap of kanthal 28 a-1 and it will blow your mind. Thanks to emontty for that one. Holy cow!
Hi, guys! Are you insert 70mm. width of the wick in stock wickhole?
One more cancellation and I'll have yours ready! and that's 0.5 ohmsDarn! I'm so close to getting those caps!
So today I have a 1.0 ohm 4/5 wrap of 28 KA-1 on a #500 50mm*33mm wick. I used the drill bit method to install the coil first then dropped the wick in. WOW!!!!! I almost don't see the point of using 70mm of #500 when 50mm works just the same.
Also, might I note, that when making the wick and coil in this fashion I'm able to just pull the wick right out whenever I want. This is a great work around for running two wicks and refilling the tank.
As well, my airhole is aligned with my wick; and while using a ONE wick setup, I did some experimenting by turning the cap and lining the airhole up in different directions, such as 90º or 180º to the wick hole. Vapor production was reduced a little, but flavor and throat hit was increased greatly. So my thought is, when running a dual wick setup with one airhole, you should get massive amounts of vapor from the wick with the airhole while getting well increased amounts of flavor and TH from the wick without an airhole. I'm going to try this tonight.
Now, if I understand correctly, if I have a 1 ohm coil on each side (two 1 ohm coils) that would be a total of 0.5 ohm resistance, correct? Or would it be 2.0 ohm?
One more cancellation and I'll have yours ready! and that's 0.5 ohms
Got my PM and paid for my cap yesterday! Suspose to be shipped today!
Anyone know of anybody that does refinishing on PV's im looking to get the orion finished in matte/satin.
