I dont recommend G rosea any more. most of mine tend to be moody. I actually have one that throws threat postures more often than my obt. Euthalus sp red is a good beginer T. even wc adults are extremely docile. also Aphonopelma abberans are very cool and calm, there's a ton that make good beginer Ts but it also has a lot to do with your own personal comfort level. if handling is desirable the ones that I mentioned are great. if you are a look but dont touch type then theres hundreds that would be great first choice.
