I bought an ego tank system it worked great for about a week. Have tried lr atty and more rr attys. If i put on a new atty it is hit or miss if it works. So i tried dual coil 1.25 and loved them for 2 days. Now all i taste is metal. When the dual coils need refilled to do not work very well. I guess dripping is all that really works. What are the best attys for dripping on an ego?
