Long story short, I was looking at what the Thrixopelma ockerti is going to cost me and I'd be able to afford to throw another T in... two that really caught my eye (though I'd only be able to choose one) are a 3/4" Phormictopus auratus and a 1" Ephebopus uatuman.

So the question is: should I throw one of the two on - and if so, which one?

It may help to mention that my mother may have a small canniption if I get 2 instead of one but I may be able to sway her lol.
