dude, sour d is a-m-a-z-i-n-g. then again, so is northern lights and purple haze. i'd have to say that's my top three, in order. sour d has a great taste, the northern lights i've had were homegrown so they were superdooper dankiddy dank, and purple haze... well, you just can't argue with purple buds that taste oh-so-good and get you hiiiiiigh.
of course, anything homegrown that i've been a part of has a place in my heart, too.
