Log vapes to be shared between 5 people is a bad idea. One is because a log vape won't retain it's heat and come up to vapor temps between hits as quickly as some other vapes. Secondly is passing a log around that is attached to a short AC cord is cumbersome at best.
SSV, imho, also isn't the best idea because of the learning curve required to get the most from a whip based vape.
The Cano, especially at that price, assuming that it is in good working order, is the best choice. NO learning curve. Just pass the bag around and suck.
