All blades should fit a standard shaft, unless you're using some interesting shaft with those short low kick point ends.
Even if you have one of those beveled easton shafts, the ends are usually square for compatibility with standard blades.
If you're looking for something with a "lethal" curve that's almost illegal (maybe it is)
Try the Reebok series blades. They have a few different curves. Some curves really big, some more moderate.
If you shoot left, there's a few at Cyclone Taylors (Oak St Location)
They aren't pure ABS though (like the Easton Zetterberg), so they won't last you all summer.
They are ABS core, with wood exterior. But they grind away nicely, as in you won't get that "flappy" layer splitting effect. The wood doesn't peel off.
The blade itself is much lighter than the pure ABS ones too. And even a noob like me can shoot well with it.
I really like that blade. Downside is that it isn't as durable on concrete, but definitely better than wood or composite...
