Well I have. Rolling them on a sheet of glass is more than good enough to see if they're not straight. 

You must be a rough guy, Kevan....wrecking Slotit axles for fun????

Yes, rolling on glass is one test but there is another, do you know it?

If you are entering a proxy and want to bullet proof your car because you know some idiot driver will abuse it then maybe harder drill blank axles may give you some relief but I dont usually choose axles based on hardness.
