Overall, I've usually liked celluloid picks because they get a slight "stickiness" to them as they warm up or get damp from finger moisture. Whatever the cause, they are less likely to slip from your fingers while playing than some picks made from a different material. That being said, these tortex picks have a nice feel and I like the gauge of the orange picks. For the moment, they are my go-to pick for playing at home and my guitar students like them. I ended up putting in an order for a larger amount, because, as you probably know, you can never have too many picks.
