of course his will be a little different. he's done some independent work on the strain to boost productivity too. i'd love to see ANYONE do a shootout between the two, but everything i've read so far says that at least compared to OTHER hack herers, sannies' f7 is closest to the original. $175 price difference is A LOT to many of us when i don't even like spending $100. i give sannies the nod myself as his rep for putting love in his gear combined with quite reasonable prices give his JH bargain status. if sensi ever gave their herer away as a UFO, you can bet i'd place an order for something at attitude. that last 10% or so in quality isn't worth a 450% price premium to me when there's so many truly satisfying strains in the $50 or even less range. that's what i'd go for too if it weren't for that name that totally offends me like TGA subcool's equally evil named jack the ripper... two of the trippiest indoor hybrids both sharing necrophiliac names. oh well, there's always malawi gold etc. maybe jack f7 is more like slightly stony, but functional, jack's cleaner 2 than i thought, but that's OK. a little stone that doesn't put your butt to sleep isn't the worst thing in the world, especially if you get nice yield in return. if you TRULY want "the real deal" in an old school trippy sativa, then skip hybrids and just go to the source. there's a fare selection of landrace gear at ace, gage green, cannabiogen, holy smokes and world of seeds that aren't going to be watered down hybrids. for me, a strain that isn't JUST about being stoned, or even stoned with euphoria, is good enough. motivation in moderate doses is nice, but that can go too much in the opposite direction too. try as i'd planned, i couldn't sit still on kali mist to listen to tunes as it just made my mind race too much, so i ended up cleaning house on it. these days i'm liking more balanced buzzes that aren't too stony or racy, especially if they have euphoria and sense heightening psychoactivity. i've only tried three jacks so far, cleaner 2, CH9 jack & autojack, and all three were nice with different personalities with JC2 being awesome and even "unique" because that touchy feely effect ought to qualify it for TRUE aphrodesiac status. if i could afford it, i'd do a shootout with jack f7 & sensi herer. oh yeah... for trippiness, sannie himself recommends 50% amnesia jackhammer too. maybe i'll get that instead of jack f7, but i don't like spacy strains that scramble your thoughts. that amnesia name has never agreed with me.
