In my experience it's not the progenitor of desirable traits in smell, taste, high, bag appeal or yield.... not any grower's favorite plant.
I'm not telling you they're guaranteed to be bad, I don't see how you couldn't get some good plants out of them. The market is so saturated with fire at this point that it's hard to recommend pirates. Especially at the price point and considering the potential age of the stock... early 2010s this would've been in more people's grows.
It might tighten up the structure of a haze hybrid and shorten flowering time but beyond that there are no real positives. It'd be something you breed away from after selecting plants out of the bx generation that express as much of the other parent's traits as possible.
If you want to advance a strain one more bx or cross it to another clone only and incross from there it might have some use. I certainly wouldn't be looking for smoke out of these if I had a plethora of options.
I'd guess there's probably something on the market that's probably superior breeding stock for the person just chucking. Looking for linked traits might be easier with his work but that requires more investment of resources, holding males past female selection, you know.... real breeding.
At this point in time these are seeds nspecta made for himself more than others imo. I anticipate that he's either got them advanced a generation/more or plans to do so at some point. If he released a bx2 ix I'd be all about trying them.
