Jazz III picks worth the effort?

They have an Ultex Petrucci signature Jazz III now. Took forever to get some, since they just came out, but I think they're a nice little improvement over the normal Ultex and Ultex 2.0 versions. They're 1.5mm, polished edges, etc. Glide through strings nice and easy.

I've just discovered the "Black Ice" picks from Planet Waves and really like them. Gotta try the Petrucci one.
