Just don't get it ... I've got 5 novas here..cartos, cartos in
tanks and a rebuildable on the way
I have never got the "muted" flavor or lack of vapor production..with any of them, minis, regulars, stock heads..different ohms.. - asked Pbusardo about this and he said the Nova gave him one of the most enjoyable vapes he has had including flavor, throat hit and vapor production...
I find they can be a little fiddly .. but no more than most anything else and when it comes to cartos in tanks - some are good, some not so much.. alot like what you hear about Novas and anything else really with the exception of RBAs which seem to be universally good but also is dependent on your mindset..
I think it just comes down to personal preference frankly... if your willing to work with a piece of equipment and figure out it's idiosyncrycies..it will probably work for you ... if not .. you just move on ... but I am not buying that it is a common performance issue.. in some cases yes.. due to product defect .. but outside of that .. just whatever you dig
