So I don't know if you decided to bite the bullet on it already, I just got a UDCT, 1.5ohm dual coil myself, and popped it onto my SLB ego-V (same thing, but V2 so 1300mAh), and I'd say the performance is decent. WAY better on the Vamo though I think because of the RMS voltage monitoring. The other APV I tested it on was the eVic practically the same vapor production and TH, which leads me to think argh, I should've gotten the Vamo first since it's alot better than the eVic for half the price.
