I've got a couple of really vicious female marcianus... But as a general rule my females are calmer.

My Cuitzeos are probably most nervous. Although the female will happily feed while wrapped around my hand. The male doesn't like being held, in the past he was happier being held by the wife than me though.
My tetrataenia male is confident in the viv but doesn't like being held.
Then I think my cyrtopsis are next most nervous. The female is fine if I dig her out, but I don't often see her out in the open. The male is the only one of mine that has musked me frequently.
My infernalis are skittish when I try to get them out, but do calm down after a minute or so in the hand. Although interestingly they do come the the open doors of their viv quite readily and will check out my hands when I keep outside the viv.
Marcianus can vary depending which way the wind is blowing, my vicious pair are always snappy though, my other two are either really friendly quite skittish.
My three radix are all happy to be held and I don't have any problems with them coming out.
