I'm only going by what he told me. He said it was hard to clamp. I believe he was referring to the holder plastic somehow contacting the clamp or gettting in the way somehow. Kind of like it used to with those carbon fiber easton holders back in the day.
I used to sharpen and profile with him at the shop and I am very well educated on things like pitch, radius, hollow, etc. I have also heard good things about Max Performance Sport's Pro Sharp Quad radius. I haven't actually tried it myself. I profile my own steel and I still skate on a standard 12' radius that I pitch forward slightly. In my experience with Step Steel in most holders, the pitch is quite consistent and usually comes so that the amount of steel that protrudes from the holder would be slightly taller (say 1/32") in the back of the working radius than it is in the front. You can measure it outside of the holder and find roughly the same result. This is not the case with some steel. LS4 steel would often come taller in the front with a very bulbous toe shape. What my friend was saying about the Step Steel for the VH holder was that it was taller in the front, thus creating a reverse pitch effect. Of course this can be corrected with some reshaping of the blade and all holders are pitched forward, so yes it does counteract that effect. I just feel like steel should always come neutral or forward pitched slightly because the majority of skaters like it that way. I don't personally know anyone that likes to skate on a reverse pitched blade. It seems a bit strange that the steel would be different in the VH holder than the other Step steel made for other holders.
I don't have any pictures. I will talk to my friend again and get a more detailed explanation.
By the way, I totally agree with your racecar analogy. That's the approach I take with my own skates.
