Good blade for inline hockey indoor/outdoor surfaces?

I used the Easton X ABS blade but they are hard to find in stock in the right size. Any other blades that will last long (can withstand indoor surfaces and concrete outdoors?

You can really use anything indoors, and on sportcourt outdoors, but to play on concrete, you want something more durable than a composite. Since concrete will wear down a blade (depending on how rough it is), I suggest getting something fairly cheap. There are still enough polymer blades out there that are tough enough for concrete, yet still fairly light.
