alright, this search led me to choose:
Satori + AfghanKush X Yumbolt from Barcelona La Huerta shop has them both on his list, i will call him hopefully to confirm that they are there
Chernobyl from Amsterdam Seed Center
Tungilope and one or 2 more strains probably from DNA shop Amsterdam
Amsterdam Seed Center and Paradise seeds are in the exact same location and DNA shop is a very short walking distance
my first trip to Amsterdam in 2000 I remember what happened, I arrived and I had smoked before I departed, got there, walked to the first most apparent coffee shop near central station, The Grasshopper, bought some weed, a skunk if i recall correctly, it was a ripoff, but nonetheless, i toked a long joint, began smoking it, i could not get to the middle of it, put it off went out to the streets immediately, i was more high then i ever wanted to be, didn't expect me with my tolerance to get so high, and in general, reputable coffee shop weed was all in all so potent, i am trying to get to that level. Don't get me wrong, my favorite strain that I grown so far and still grow, William's Wonder, is dank, great stuff, everyone who smoked it agrees, but I KNOW that I have had stronger stuff and want to grow some of that. I hope i get it right this time, cheers
