I switch back and forth between my grippy Pro D (mostly for putting duties), and a nice softy (usually for driving, less rollaways, wet conditions, colder weather, putting when the other one isn't working quite right

).
They both seem to be wearing in very predictably. I'd say I much prefer the release of the pro D for longer putts and jump putts, and much prefer the x soft for driving, in general. In the New England winter, I doubt I'll use the pro D much, if at all.
Cryztals don't even feel like the same disc to me, not a fan at all. They feel too deep, and are squirrelly as all get out.
