Yes, I have to agree, the Afghan pheno I had was not as tasty or potent as the Arcata pheno, for this reason I discarded the Afghan pheno. The seeds you have are the result of crossing the Arcata pheno female and the orangery pheno female to the most sativa leaning male (he looked like the Arcata pheno a lot), the reason for choosing two females was that they looked almost identical but had different tastes and I couldn't decide which I like best, so I decided to preserve the variation and use both.
The yield of the floppy one is indeed impressive if you get it right, it needs to grow as a big bush with as many budsites as possible.
So I think the floppy pheno you have is the closest to true TW whereas the short chunky pheno leans towards the Afghan part of the line. The floppy pheno, if it's like the ones I had, will have a soaring, immediate 'oh my, I'm rather high' quality and the taste is very sharp and strong from the first toke, if the Afghan pheno doesn't have these qualities, discard it.
One thing else I will say, looking at that Affie pheno if yours is that it gives ya some insight into what a TW x indica woul look like, now go and look at GHS TW grows and you will see that there also looks like a TW x indica of some kind, so if theirs is pure TW I'm a monkey's father's brother me old china lol
