Roads are fine, but I actually blew them out with gen 1 Road Magnets (which are lower just like gen 1 hyperco were), and Hyperco are kind of soft for my taste anyway.
Although I have blown a few on hyperco/agx. On another B13 when I lived in NY back in 04-06. NY has some shitty potholes and it takes is a few and they are done.
My point is that the AGX will hold substantially more abuse but they aren't the toughest either. The CSK really has a lot of benefits if you're willing to go through the extra work.
