Well, in my personal experience, Ti (my experience is limited to 6Al-4V/AMS4911) is much more flexible than steel when it gets down to lock pick thicknesses. It flexes a lot, but usually doesn't bend - it has more 'play', but it usually just flexes and springs back instead of staying bent permanently. If you make the thin section too long, it can make feedback feel different than steel picks - not necessarily bad, just different. It's a little bit springy.
I make my Ti picks with a little more meat on the shaft than my steel picks. Where the shaft ends and starts tapering into the handle, I try to keep that close to .100". I make the shaft 1.5" long, BTW. That seems like a good length to me - able to comfortably work in a 6 pin lock, but not so long that it gets too flexible.
It took a little trial & error before I settled on those dimensions, but so far they are working well.
edit
I'm interested in finding out if the CP stuff behaves the same way. It's about a third of the price of the aerospace stuff - just wondering what the 'compromise' is to make it that much cheaper...
