Just a quick reply to the OP. I've grown about half of TGA's varieties, and based on what the OP was looking for, I'd suggest Agent Orange. As the TGA web site itself says, Vortex may be the most stable hybrid of the herd, but Agent Orange is also very stable and a good yielding plant with the AK characteristics you mentioned, IMHO. AO is the primary strain grown in our medical operation, and is what we offer as our mainline offering to patients. Is it the "dankest bud on Earth"?....No. But I'll tell you this much....it's the "dankest" of any strain out there that will consistently give you high yields. In my opinion it's the best commercial strain to grow if you are looking for a cash crop but still want very high quality. Since it's a 50/50 hybrid, it meets a wide range of patient needs, and the more resinous of the phenotypes makes great hash and strong edibles (we let all the phenos grow).
I don't work for TGA and subcool doesn't know me from Adam, so this isn't meant to be a commercial. Just saying that after growing over 30 strains, including 10 from TGA, Agent Orange is the best all around strain there is in terms of a high quality, good yield, stable hybrid with wide appeal to patients, ease of growing, and a shorter flowering period. We chop our AO at 56 days regardless of anything to maintain a very strict perpetual grow cycle with 2-week in/out intervals, and she's always ready and looking great.
I really can't say enough about this strain. Great work by subcool and the TGA crew.
