I think it has more to do with the atomizer and wire other than pico vs. Evic. I've had unreliable results using avocados with even single SS wire. I've even had SS Clapton wire either not work in TC from the start, or sometimes work days later in TC after vaping in wattage mode for a while. I hope to have better results with a new atomizer I just ordered...the Serpent RDTA.
