I do love a Kush, never smoked one I didnt like, I think I like them because they are usually hybrids around 50/50 Sativa/Indica. That said, Nirvanas old Misty Kush is a favorite of mine but they changed the parents and stopped selling them on this side of the pond. Rainbow Kush from AMS is top shelf and I have not smoked it yet but Unknown Kush from Delicious seeds will probably be my #1 choice after I get a chance to grow it out. Those 2 have a really strong blueberry smell to me, very sweet, no fuel smell at all. I have not seen a female Spartan Kush yet but the crosses are top shelf.
