Doubt you will get one off the shelf but easy to recurve even Craig could do it! Use the same springs and ask me for a cam with the same slots. Who knows what happens if you ask nicely!
I am kind of an odd duck when it comes to asking. I have no problem asking nicely if I first ask. But, I have a tendency of not asking at all because I do not want to bother anyone with my issues. And if I ask, I always ask what the price is, and agree about it before the service is given.
