Only issue with going for higher res on an eGo Twist is that you'll lessen your battery life.
(This is the point where new vapers start getting confused. LoL)
Ahem... Quite the opposite. The lower the resistance of your atty (and the higher the voltage), the faster the battery will drain.
In other words, higher wattages drain batteries faster than lower wattages.
Wattage = Voltage squared divided by Resistance.
