Yeah, I was thinking the culprit was the atomizer/ cartomizer difference...but I will continue to give the REO a fair shot. I may throw a cart on it and see what happens..
There is more of a learning curve with the Mini and a atty. But that Mini will perform better when you can get the squonking down.
I can understand how it is easier to just pick up that other one and not have to mess with anything. But if you really want the best you will have to work for it a little.
The Mini will blow that other away when you get it right. I hope you are using the AW IMR 14500 battery. They really do make a big difference.
Keep trying, maybe try the cartomizer it will be a little easier and more forgiving at first.
