All I ever use is map tanks. I don't think you will ever get the same flavor if you are dripping, too many variables can change. Kind of funny, first time I tried the GJ was dripping, didn't quite get it and was not sure. So I just filled up the Map and fired it up. Since that day GJ is in my top 2 juices!!! I always have 2 flavors with me and now GJ is one of them. I use the 2.8-3.0 ohm at 4.4-4.6 volts in my Buzz and love it!! I still love the flavor on my Ego battery also.
The one thing I will note, as you get lower than half full in the MAP Tank, I have noticed a decrease in flavor with all my juices. Once I top it off it comes back. It will start to lose flavor after about 1-2 tanks, it needs to be cleaned and dry burned. Then all that flavor returns!!
As far as wicking goes, I have the opposite from most. Mine seem to wick too well most of the times. Once it gets lower than a third full, I have to do the tip then vape routine to keep from getting the burnt flavor. This happens with all my juices, I now only vape 100% VG also.
Hope this helps some, I tried most of every kind of Carto, atomizer and set up you can think of. After all that $$$, I realized that I am lazy and the simplicity of the 5ml in the Map fits me perfect!!!

Fill once every day or two, clean every 3rd or 4th day and repeat! Remembering the extra batteries is another story
