I use BB exclusively in my Ody, and its taken me quite a while to get it figured out.
First let me say I have used the iAtty since it came out, with BB, and its really good. I anxiously waited for the Ody for months but have had a rough time getting the same vapor and flavor out of it that I did from the iAtty, until using the following iAtty trick.
I tried tweaking the ohms, and several other ideas that I thought would fix the problem, and give me the pleasure that I have with my iAtty. The problem is the short amount of wick accessible to your juice. The trick to fix it is very easy and very effective, it allows a lot more juice to make it on to the wick and hence the coil. The end result is a richer, smoother, fuller vape.
The trick is as follows:
Make your wick and coil but DO NOT tuck in your wick. Instead of tucking your wick in the slots and then attaching it to the base, attach the top and bottom and leave the wick out of the bottom. Take your long wick ends and leave them out side of the ground "ring". Let the top "cone" mouthpiece hold the wick in the slots, nothing else, the wick will be free to float in your tank full of juice. You can adjust it just like you usual would, and its perfect. Just take care to make sure the positive wire is not making contact with the ground "ring" since the wick will not be covering it up.
If you need a picture let me know, but its the same idea as the iAtty used, all of the wick is in the juice.
I hope this helps.
