I think he said "beats GVG anytime" before editing the post implying he's already tried it?

Personally I believe it only if the GVG is used with inappropriate technique. As I don't believe persons weight has such noticeable impact on the dose required(well maybe +/- 10mg at most).

But I really like the extra space for vapor, I wish they would make a glass vaporgenie piece as I don't like the idea of melting it with open flame...

Well what matters is that it works for cyantific well.
