My usumabara isnt arboreal , and my king baboon is still quite small .. its just the fac of the cage i dont have a good one yet for an arboreal of that size.. i hear there lighting quick.. but then again... so is spaz (my usumbara).. er idunno i never actually seen one in real life i just heard horror stories lolWhat I dont understand is that you have an Usumbra and a King on the list and yet you say you are not ready for an ornamental. Let me tell you, an Usumbara will make an Ornamental seem like a baby kitten. Pokes arent as bad as what people say about them believe me. One of my 1st spiders was a P regalis and now I have 5 Pokes and they dont hold a candle to any of the African species as far as temperment is concerned.
IMO the best display species are Brachypelma and even Acanthoscurria spp
