For flavor recommends I usually go with something many people around me that I let sample my stuff have really liked, not just what I personally liked as obviously "good" is only relative to the person tasting it. For sweet flavors noone yet has disliked my cheesecake and strawberry shortcake from madvapes. (topvapor)
The thing I'm surprised that noone has mentioned is what is he vaping on? When I ditched my volcano for a 510 there was a noticeable difference in flavor strength then moving to a LR atty there was a big difference in flavor strength. Then you have to figure in the muted flavor from him recently quitting as others have mentioned before. There's a good chance there is nothing wrong with his current juice. He may just need to evolve to a better PV?
I totally agree - my VGO 900 just died
