BPS, I'll agree they are similar, but there are some differences. With the Hoyt system that Newberry also uses, the top "cam" has an oblong lobe that makes it necessary to have the cams synched very closely to get a firm wall and decent nock travel (I'm told), where the CPS has all of the "important" stuff on the bottom power cam. The Darton and Champions have an extended lobe for a firm wall, while the Pearsons do not, though the Pearsons do have a slot for adding a limb stop. My "calcific rotator tendonitis" gets along much better with the earlier peak of the Darton system than the later peak of the Hoyt system. The Hoyt can also be tough on power cable serving, while none of my CPS cams have given me a bit of trouble. They both are good, and the Hoyt system may be a little faster. I know the B1 is just about the fastest bow I've owned, aside from the Patriot Dually and the Oregon Black Knight.
