See right there's why there is no single right answer to this question because I'm completely opposite in my practices but I get the same results.
I've found that mine get really irritated when I mist them down and I get bit more often after than before. With younger ones, I also tend to put my hands in right over top of them and bring them off the perch that way... I don't pull them off, but I encourage them to come off on their own.
All of ours are handleable, but some are less friendly when you're actually reaching into their personal space (for lack of a better word) than others. Even the largest adults that I handle at work are fine once you get them out and I actually do public educational programs at schools, etc. with ours (obviously I don't do this every day as I think that would be excessive, but it's fine every so often).
