Any newer hybrids approaching the potency or topping the older strains aforementioned ?
I did oldtimers haze but I think it and Malawi are really close in strength. A Malawi Breeders pack will likely offer the most variation of powerful sativa effects of anything Ace has to offer while still being 90% homogeneous. That Super Malawi haze will be insane I bet. That and oldtimers are likely the strongest "haze" types by a long shot. Golden Tiger got a ton of votes and I guess I can see it. It is a powerhouse of a strain but 90% of it's effects are in the psychedelic side of sativa effects but it does have some "downer" type body effects that I don't personally associate with pure sativa type effects. I'd be hesitant to say that Golden Tiger represents the best of what I consider full sativa effects. All that said what I think will really be the most powerful sativa Ace offers is something not for sale yet. That C5 haze x Malawi is gonna be a fucking beast as are a couple of the new Haze, malawi killer stuff on the list. The Malawi line is hardcore, breeds true and has always produced reliable powerful sativas. The Oldtimers is more of a hunt but she's without a doubt some of the haziest haze I've ever had. Golden Tiger is for sure trippy but comes with some minor body relaxation stuff that I don't think most people consider sativa effects (maybe from the slightly higher CBG count?) If you want sweat and be paranoid and slightly trippy I'm think some of the stuff on the RnD list will be right on target.
From your list from before I'd do Oldtimers and hunt for a purple. I got a purple and green in 7 seeds or something silly so it wouldn't take much to find one. She's a real bitch to keep under control indoors but I think you'll enjoy every second of her smoke.
Destroyer from Cannabiogen is another powerhouse of a sativa hybrid. As a matter of fact I can't think of another strain I'd look for if I was looking for a sativa hybrid.
