The max-grip surface makes a big difference with the standard jazz3 size. They do max-grip on most of the jazz3 line now, nylon(red) and stiffo(black) too. IMO it makes more difference than going up in size to the XL-jazz3.
I use the Jazz lll and love the red and black ones. My very favorite is the Ultex yellow version. They have the perfect amount of tug coming off of the string for me.
I tried the max grip ones, and hated them almost immediately. They stay in place well, but if the pick gets twisted in your fingers, it's almost impossible to get it sitting right again without stopping playing. I can make the other versions twist back to where I like them with only my picking hand.
