I know you're in Holland, is Sensi Seeds the same as the used to be? Many people are saying their strains are different now. I know they have a lot of the original strains. What do you recommend from them and the Flying Dutchman?
Those people highly overestimate what Sensi was in the first place. In some ways it's still what it was, one of the best places to get crosses based on the oldies, and some of the oldies themselves. Once that simply meant the best seed collection one could buy from, as in the best seedbank.The stories about how those and others are no longer original are especially fueled by seed banks who had/have Neville as a mascot 10 years later, GHS and MNS.
After the many initial skunk/afghan/kush/haze/NL crosses the next obvious step was three way crosses which do not produce uniform plants with phenos leaning to all three (grand)parents. Especially the haze varieties are clearly better for breeding and/or finding keepers than growing something consistent from a pack. I also got to say their germination rates suck (from the store anyway).
As for specific recommendations, that depends a lot on your goals and preferences. For let's say educational purposes, grow afghani, skunk (I'd pick the pure from FD), O haze, hindu kush or master kush, and NL5#xHaze, silver haze, and jack herer.
Or, figure out what percentage of afghan/NL/Skunk/Haze you'd prefer. I personally would not bother with their NL, the early girl and pearl, and big bud, unless I wanted to source specific traits for a breeding project. I smoked and sold most of the classics in the 90s and it really never was as great as people nowadays dream. It makes me more nostalgic than high.
As for FD, I have no experience growing their strain but their original haze is original haze, and the Pure is original skunk. As original as it gets anyway... Don't let the prices fool you, it's weird really, flying dutchmen (owned by sensi now) seems too cheap, Sensi is getting absurd.
I see now FD sells afghanica... that was once the best and tastiest I smoked, in 95/96, made everything else smell blend. I don't know if theirs produces the same phenos, but this is one of the most accurate pages on wiki lol:

If I didn't have enough going in already I'd buy that one tomorrow just to see if it's.... original.
