In laws are in the other room, so I'm in here, playing around on ECF. For what its worth, I have an eVic, and can set the device to VV, VW, or set curves for each. For the life of me, I can't tell a difference between VV and VW, but I can see why some would prefer VW.
I use an RBA, and wind microcoils for a Protank II that I use as a back-up. If I was still using different clearos and cartos, I would probably keep the eVic in VW. I kept about a half dozen clearos and mini clearos filled with different juice. The VW may have come in handy for me, then, but I still used attys with pretty similar resistances. I ended up adjusting either the voltage or wattage depending more on the juice. Other users may have similar experiences, many may not.
I do like having options and features on devices. What is more important to me, is for something to work consistently between vapes, not necessarily between attys. This is mostly why I have steered away from mechs, but there is a horde of people that would jump me for that opinion and observation.
Having said all that, I think there is an advantage to a device that would adjust the wattage as resistance changes with heat during each vape. I find it interesting, however, that even with the ability to change the output as a function of vape duration, most eVic users use either VV or VW instead of RVV or RVW. I actually prefered RVW and would preheat the coils a bit for many of the coils that I built until I settled on the coil I use now.
So there it is. Washer / Dryer mode. That dishwasher mode has me thinking, though. I don't like dirty coils.
