Using a variable wattage mod will give you decent performance. Look for something that you find comfortable for your hand, as well as a device that has the battery capacity to get you through your day. Most mods these days, barring mech mods, will have a decent display that you can easily adjust your wattage, voltage, or temperature so you can adjust to your tastes. The vtc mini is a nice looking mod that is comfortable to the hand and not too heavy. You could also go with one of the cool fire iv or iv plus batteries for a nice sealed unit.
