The vortex if want that racey, paranoid, sweating kinda high (that's the suggested pheno if I'm not mistaken...) however as said; you can possibly get a good a13 pheno... Possibly... I'd say if you ran a 10 pack your definitely find something nice and a most likey a choice of a few phenos...
Or my favorite... The void.. aka purple Apollo 13.. I bought a 10 pack 2 years ago and originally cracked 4... Got 3 fems, 2 Apollo Dom and one querkle-ish pheno, the other looked querkle-ish but it Hermed on me because a surge protector with a nice bright LED under it... But I ran those 3 to death for a while and then had to close down for awhile chopping all my cuts of strains and having to start anew once I was able to get going again...
I recently cracked 2 more from that same 10 pack and got 2 females, 1 is kinda Apollo Dom, very purple yet I can still smell grape somewhere in it a little more than that Apollo funk...
Then the other one I have going (this is the 2nd from seed plant this time around) that looks like the Apollo momma to the T but I haven't gotten to taste that monster yet and it's pushing 60 days and still has a little while to go so I'm gonna say this one is gonna be more sativa dominant very a13 dominat plant, almost a mirror image of momma (a13).. she's in a 18 gallon Rubbermaid for a comtainer with 6-8 main heads that make the plant look like 6 (biggish) individual plants... And that bitch is big to say the least, the biggest plant I've ever flowered... If her yields are like the other one I just ran; I'm gonna be a happy pothead... I just chopped 2 clones from the other pheno I mentioned above were ran in 5 gallon square hard pots; they yielded just over 8 zips total...
The smells range from grapey, funky, peppery, cheesy, stank-ness and is a high like I've never experienced before... An up and extremely creative high if taken when trichs are going from clear to cloudy, and if you let them turn a little amber you'll get a more relaxing high but you loose flavor but gain yield and all that...
I am a big fan of tga and vortex is their goto/recommendation strain... Which I have yet to try but I didn't like the description of the high, I am not all that fond of that paranoid, sweating type of high... The high I get from the void is very up, very creative and energetic as long as you don't let it go too long before harvesting, without any of the paranoia...
If you still go with something else, keep the void on your list, definitely one of the less popular yet fucking awesome strains tga has....
