Dude if you are legit and right now you sound kinda shady but thats just me .....so back to the subject, the despensaries are always changing strains as they run out and what not so with that said you would NEVER look or sound like a dork to walk in there and ask the guy what his best stuff is for back pain and you would probably get a few different strains to chose from, then close your eyes and the first one you touch go with that one because I can tell you they all will work wonderfully then the next time chose a different one until you have a bunch of strains under your belt and you know what works best for YOU!:smokin:
