Has anyone ever heard of or used protex ultra street rotors ?

ran into a set on ebay
{DESCRIPTION}

they look pretty nice the design pattern for the slotts and drills etc
the design is similar to what i seen on V8 superutes they were saying they use on there utes

ive currently got a set of front RDA slotted and dimpled rotors unused still sitting around (waiting to get a rear set than ran into these) what ones would perform better and last longer ?

and what do you guys think would look better with FR18's ?

i like both designs of rotor to be honest and these would stand out a bit more being different to everyone else
