I guess I need to try out some Durban Poison! I really like Jack Herer and Jack's Cleaner. I also loved Chocolate Diesel, I'm hoping I can nurse the mother along well enough to get some cuts from her.
Damn near any Sativa that has that nice, up high and that will take the tops of other people's heads off is what I like.
Now that I'm thinking about though, I think I need to try more Sativas before I can really say.
