Does anyone know whether or not these cams are similar, the same, or very different? I realize the Parker does not have the weighting, but they do look similar. The speeds from the bows look close for the given braces, but I do not profess to be able to calculate that stuff. Any information would be appreciated.

You may or may not want to do this, but you could try contactin Tink Nathan at AT.com

I believe he shoots Parker, and I see more posts on Parker from him than anywhere else on any forum...

They are similar but the draw is a bit different. The Parker feels more similar in the way it drops off into the let-off to the other Parker bows than Mathews. They shoot quite nice.
