Hi, i'am a beginner vaper and i'm vaping on an istick pico with the melo III mini in the box there were 2 heads 0.3ohm EC heads and 0.5ohm EC heads my question now is: what are the differences between the 2 Heads? Is thereone that produces more flavor/vapor? I mostly of the time vape on 45W-55W anyone can help me? Greetz Alex Sent from my iPhone using The Vapor Talk mobile app
