I don't drip so I can't help you much in that area.
A mod like the "Lambo" won't really give you a better vape. Volt's are volts regardless of what
device you use.
You will get more bells & whistles like an LED voltage reading and battery level. You can also check the resistance of the
device that you are using, and has more battery protection built in to the
device. This can be very useful if you want to eventually get into rebuildables.

One other advantage with a mod is that you only have to replace the batteries (~$10), whereas with a twist you have to replace the whole device ($20- $30). The batteries are usually only good for about 300 recharges, so the mod will be cheaper in the long run.
You don't mention what juice flavors you are using.
Myself, I like NET's (Naturally Extracted Tobacco). If that interest you should check this thread for recommendations.
