Any DutchfriENTS from Leiden/Den Haag? I need to know your favorite weed strain!

Please don't downvote this into oblivion if this post is not related to you, that would be very unfriENTly ;) Like I said, I'm from Leiden and I've been smoking for quite a while now. I always buy the most bought weed but since I have new work I want to try something fancy. Something new. What are your favorite weed or hasj strains and in wich coffeeshops do you buy them. Any good Sativa recommendations in Leiden only?
