Look at the name. I'm a former OG'er, I get scientific with this stuff. I own a RooR and a 6 footer and aside from that I've made everything else I smoke out of. I'm not too bad at rolling joints, but truthfully I've never rolled a blunt in my life. As far as knowledge of the good cannabis, I can tell you about growing (guerilla growing; indoor closet; indoor stealth; outdoor stealth), harvesting, curing, breeding, hydro and/or organic grows, and just about anything else.
