Cross Drilled Rotors - Who uses them?

[2FastLX]

I ordered Power Slot slotted rotors, but instead I received Power Stop's cross drilled rotors. I've heard that cross drilled rotors are prone to cracking so I'm kind of scared to put these on my car. Power Stop says these rotors are intended for street use only so they should be fine right? I really need to get my car back on the road so my only other option would be to send these back and buy some stock replacements. I don't race my car much, unless a Camaro pulls up next to me, and I rarely take it to the strip (twice in a year and a half). What do you think I should do?

After seeing these rotors they appear to be very well made and the holes in the rotors are chamfered which would help prevent them from chewing up the pads, and prevent them from cracking as well I would think.

Thanks.
