Putting a new cam in my 360

I don't want to badmouth ken, but he can only copy a lobe. He can't design a lobe. He has a bunch of masters made from cams that have come through his shop, several of which are mine,because he had to repair the lobes I tore off with junk lifters.

It is also very difficult to copy a lobe, and then put it on another cam. I know it's done, I've watched it, but it makes me very uncomfortable.
