You made the right choice , I have both a Vamo 3 and an SVD . The threads on the Vamo are crap and I also have both protanks and the Aspire no contest here either . I constantly have to rewick the protanks due to flooding , gurgling or the opposite dry hits depending on what juice I'm using they are a major PITA by design and I don't care how many coils they stuff in a head it'll probably be twice the wicking issues . IMO the Aspire wins hands down the only thing I should have to rewick or rebuild to get it to work properly is an RBA or an rda . I've had zero issues with the Aspire .
