The great thing about the Vamo's VW as opposed to the VV is, as stated above, once you have found your sweet spot where you get a good flavour, vapour and Throat Hit, you don't need any further adjustment. Swop from a 2.8ohm clearo to a 1.8ohm Nova and the Vamo (or indeed any other mod which uses VW) will automatically supply the right amount of heat to the atomiser to produce the same results.
So it is actually easier, as ZT says - once you find your setting, no more faffing about!

ETA - Apologies all - serves me right not reading the rest of this thread before adding my comments! This should now be explained in about 5 different ways, but the premise is still the same - VW is cool! (Or hot, depending on where your sweet spot is!!).
