After 7 years of vaping I'm finally going to get a RTA/RDA...I use an old crown 1,falcon king and an Uwell Nunchaku...Flavor is most important factor..I was looking at the Unity so I wouldn't have to buy a squonk tank for the profile..My e liquid supplier went to the RDA and a nice squonk tank,he loves it...Those that use both what is your opinions between the two and would I get a nice boost in flavor from what I use now?..I would get a squonk tank if I had to..Thanks for any opinion,Bob
