Ran an IkenVape platinum carto in my VV Grand today, very nice. Excellent flavor, don't have to pay as much attention (with atties I have to be careful to not over fill the drip well).
Using a 2.5 ohm Cisco spec 306 atty right now, since I liked the lr version on another mod. Hoping the longevity is as good as I had with the lr. It seems to be easier to work with on a bottom feeder than the io6. I had enjoyed the vapage amg hybrid, but their 2.5 ohm don't have the design improvements now found in the lr, the pair I had fried too soon.
