I must say, as picky as ZFM is with regards to technique (and in my case, brand of atomizers), it hands down gives the best taste, consistency, and vapor production I have experienced.
All the other mods that deal with ANY type of filler just don't provide the full on taste that I get with ZFM.
I had some problems with non-Joye atomizers not wicking properly with ZFM, and as a result the taste just wasn't there. While waiting for my new Joye LR attys to arrive, I had to resort to standard polyfill and the ADM, and it just wasn't the same.
Long live ZFM and Scottyballs!!
