I go through periods of trying a lot of flavors, and periods of concentrating on a few - either way I still prefer vw over vv myself. I really do find it more convenient - and I have a number of pvs that have both options.
Goes to show every one is different, I rotate between 2 or 3 flavors during the day I've experienced no benefits to my vaping style using VW over VV.
I ended up fiddling with the VW devices I've owned just as much as VV devices to get what I want out of a PV.
