I just got a new mod a Smok R80 TC. I have been using my Istick 30 with the Melo2 and it worked OK. 30 watts with a.5 coil was OK. Now I have more power and the Eleaf .5 coil is rated up to 100W. I experimented last night up to 50W with a new coil. I was wondering what range other people were using to get the most flavor.
