I ordered a [FONT=arial,helvetica,sans-serif]1300 mah VV pen with [/FONT]a Protank 3. What Ohm dual coil would give me a good vape? The reason I ask is that I bought the Mini Aero with a 800 VV pen that came with 1.5 ohm dual coils, and couldnt get a substantial hit off of it until the store let me try a 1.8 ohm dual coil, made all the difference in the world! How can one know what ohms to use? Thanks for any info!!!!
