I think you'd have to be pretty darned patient to wait until you could get some bare cams to try that trick anyway!

Then your draw stop might not work properly with the limb angle and your bow could get locked at full draw, 100% letoff like I did once to my Firebrand Discovery. You would probably change draw weight significantly, etc. etc.

I wouldn't be too surprised to see a supply of these in various lengths in a couple of years, much like you can buy draw length specific cams like Mathews on Ebay any day of the week. Be sure to use them responsibly, Russ!
