Ok some initial impressions. first thing i noticed is the HI runs hot, really hot on full blast on the vv adapter. but after a few bowls i think i'm in the right zone for temps. I didn't order any roasting tip but i'm ordering the ss slides real soon to try it out. with the standard turbo tube and glass tubes air flow is crucial, i over packed once and combusted really fast. but after that i adjust the way i use my HI, i find that if i use it like my lsv i get some really tasty cloudy hits. don't expect to just stick the turbo tube in and draw away, with the HI you have to consistently adjust the air flow to prevent it from getting too hot. i've only done a handy full of direct draw bowls, but i actually like the standard silicon tip more since it feels better on my lips and the draw is a little more restricted which i kinda like, although the glass ones have better taste. its only been a day so things may change.
OTA, with the vv adapter and air flow control you can get the abv as dark or as light as you want. i've gotten both the lighter abv you were talking about and a very dark abv too.
