yeah my 1st grow of headbanger was pretty potent to some... i can take 12hits and be stoned, but i'm always looking for more - on the other hand, i turned some friends on to it at a wedding, who are lighter weighter smokers then i am, one sat in his chair for an hr b4 moving, the other guy i thought was going to pass out at the dinner table... i was getting nervous , but he too recovered in about an hr-. As far as potency a cut of headbanger blew away every so called elite i ever had by far.
