Interesting post, and I fully agree. I have had more mature males than females, and people often say that I should find a girl T and breed the males. I have not done so (except the H Incei because the slings can live communally if not sold).
The main reason for not breeding my Ts is that I think the market can be flooded, and I would not know what to do with so many slings that cannot be sold, and also I know it requires a lot of time and care, and really, I prefer other people doing it. And the main reason - all my Ts are to special, and have names, and I would be devastated if any of my males becomes lunch for an agressive girl!
You can distinguish people who are in it for the money and people who are in it for the love of the hobby clearly. And I know who I will buy spiders from, and it is not the former.
