The everlasting search for RKS continues...
Everyone who is searching for those true rank Skunk terps are going to be disappointed if they search through Skunk1. Even SamSkunkman admits he bred away from the Skunk smell as he preferred the high from the sweeter types.
Much of the true Skunk-Spray smells could be found in many of the early Afghani varieties, and are where I believe the term "SkunkBud" originated. Folks were calling weed Skunk long before Sam arrived w Skunk1 in Holland.
The famous Super Skunk (aka MassSuperSkunk) involved in creation of Sour Diesel was originally from Nevil's work. He bred the Skunk1 to his AfghanT which he claimed really put the Skunk smell back into the line. This further cements the theory that those old Afghans are really where one should look if you want to find the true Skunks of legend
If your super interested in the Skunk I would check out NotsoDog and Riot's BreedersSyndicate podcast. NotsoDog had lots of hands on experience w that old Super skunk and is a great source of info. Also SkunkVA's episode on ThePotCast he goes into the details of how the Super Skunk made its way from VA to Mass and Cali. Look at the polaroids he shared of the old Super skunk and you can definitely see the similarity to the Sour
Closest I've found to a true RKS stank is the Giesel cut. It's super Skunky, but also has something to it I can't quite describe. Not that pure RKS smell or taste, but the closest I've found so far
