You probably want to learn to identify varieties by leaf if you plan on spending lots of money… There are many synonyms going around, as well as mislabeled or fictitious varieties. The high prices attracted some ne’er-do-wells who chased off most of the experienced growers, so you are mostly on your own when it comes to verifying you have the right thing, and now also if the right thing even exists.
Not entirely sure what you are bidding on, but one person who was selling MR on figbid is the same who traded me a cutting from a Smyrna seedling as Yellow Neches a few years ago, that was fun to waste 3 years… There is this rumor that because a seller is popular on a forum they are 100% legit because if they were not, someone would say something, well they started that rumor and now suckers buy it and repeat it. The same suckers won’t be around next year when judgement day comes and what will they do anyway; contradict themselves and make the group turn on them? Be cautious of people using social influence to get your money rather than pictures and objective descriptions from their own experiences.
