(assuming it's on an appropriately built riser design that allows for perfectly level nock travel..not all CPS bows are).
Jeff, I'm guessing that this has something to do with where the company decides to put their bow's riser cutout. The "arrow center", must vary from one company to the next. Do you know, if true center of the bow is what they need for the best nock travel with these cams?
Exactly. A "below center" grip will help to alleviate nock travel issues, unlike the older days when on most designs the grip's throat was at true center.
Also note that bow must be drawn from that center position. Meaning you need to use a loop directly behind the arrow nock (or something like a "gatorJaws" release).
Some Pro shooters who shoot singlecams with less than optimal nock travel will nock under or tie a loop under the arrow nock as they believe it helps offset the nock travel issue. I've tried it. On some bows I felt there was a slight improvement. But it could have just been my subconcious at work
Another factor that is often ignored (or perhaps many are not aware of) is the limbs. Limbs must be of excellent consistency to get consistently good nock travel from bow to bow to bow in a production run.
