Ok, so, that makes good sense to me so, recommend one of the ones you've mentioned,I wouldn't suggest anyone get a pokie or an OBT as a first tarantula. I'm of the opinion that no amount of research can prepare you for having to rehouse one of these. I'm a big fan of the ladder system. Psalmopoeus will prepare you for speed and attitude, minus the medically significant venom. This is why species like this and Ephebopus make great intermediate tarantulas. There's no reason to go diving into the deep end. Something to always consider is if you have other people and/or pets in your home, should an escape ever occur. The venom of some Old World species can be lethal to cats and dogs.
P.ornata is one of the worst pokie species you could possibly start out with. They're among the more high-strung pokies. I'd recommend P.regalis over P.ornata for someone new to this genus.
Psalmopoeus irminia maybe or Ephebopus cyanognathus?
the P.irminia is lovely reading about them today if time permits
