Flooring for 24" on center joists? Doubled up OSB?

I want to put some flooring down in the loft of my garage to make re-wiring it easier. Plus I can use the space for extra storage. The joists/rafters are 24" on center. I know that I could use 1 x 6s or something similar, but I am trying to figure out the cheapest/fastest way to do this without having to worry about falling through.

What do you think about using doubled up 1/2" OSB? Lowes sells it for $6 a sheet right now. Which is a lot cheaper than the $27 a sheet 3/4 plywood I was thinking of using.
