Every Tuesday I have to pile up in a car and go for a 2 hour drive with a couple of guys. All are smokers (which sucks) so the vape isn't an issue. However I am still weary of vaping comfortably as I don't want the vapor to cause any imparment to the drivers ability to see. All I have are sub ohm rta/rdas, i diy juices. I haven't mtl since the first time I tried to vape. I have 28g kanthal and 26g ss 316l. I have no idea how to make a set up that would be a satisfying and low vapor producing. Any tips will help, will make a high nic juice specifically for the trips, wattage ohm, and coil build. And yes even with the windows down I feel like it still blows around the cab. Thank you kindly.
