Very good question, i was wondering the same thing, as i am waiting on my 1ST rebuildable, with vapor production thats going to increase and the burning of more juice, although at the same temperture,will that altar the flavour?+1 on this, i generally vape unflavored vg juice, and occasionally add some menthol drops. i don't get tired of it. on a related note, i'm currently developing an iPhone / iPad app for creating and tracking juice recipes, and i would love to know how juice mixers out there change their recipes for genesis mods! Do you turn down your flavor or just enjoy it more?
