The Hilliard is "machined" also inside and has grooves but its not the same. No matter what you do on the track you should get full contact pattern of the shoe...
Call me if you want a flame... $69 for flame blueprinted and setup for your class. I recommend the bully conversion kit for additonal $33 so you can use bully drivers on it. The flame itself for $69 is like a $120-$130 value if I charged for the blueprint and setup..I don't make much on them obviously. I pretty much just sell them as promotion for my business. Gets me futute work from people that buy them sometimes and then I make my money.
