I just got a sabot as a gift from Fringechief, is is designed to use a Smok ARO coil, which is almost exactly like the old kanger Pro-tank coils, which I used to use a long time ago. Your are supposed to use the ARO coils, because it has a smaller diameter flange, which fits threw the hole in the BB tank. I decided to give the pro-tank coils a try, and right off the bat it just was to low OHM's. It was supposed to be a 2.2 OHM coil. So last night I took one of my old used coils, and I rebuilt it using NR-R-NR wire, and wicked it using cotton. I then put the coil assembly inside a Boro tank and assembled the rest of the Sabot. I have been using it for most of the day, and I must say the the flavor is just as good as a Billet Bridge. If the UNO is anything like this, then I want to get one for all my BB's. From the pics I have seen, the UNO is basically the same thing, this one just doesn't have the coil head. I once again gave up on the Sophia V2, just too aggravating, I was able to get it working, but I was constantly fiddling with it. this one works good.
