im a carto and tank guy, but recently watched some reviews on the vivi nova 2.5. i like that its kinda of best of both worlds. atty and carto tank kinda. well so far im liking it, tons of vapor but the flavor of my juice seems a little muted. i hope its just a break in period. im using the 2.4 head at 4.0-4.4 on my provari. question is, im using this setup to sample some 5ml juice bottles i have. im just about done with this fill, how do i go about cleaning the vivi, in order to add a different kind of juice.? can i rinse the wicks and reuse same head?? im hoping to get the most out of this head i have..
