I have two bows that are both CPS syle cams, which tune very easily with a variety of spine. On the McPherson Edge, I have a Whisker Biscuit. On the Champion, I have a QAD Ultra rest. I have not paper tuned either bow, but I did bare shaft tune both bows with the Cheetahs, as well as ACC 3-60s which are also a bit of the stiff side. They both will shoot bare shafts straight and grouping with field points at 20 yards. I haven't tried it any farther out. The both shoot broadhead tipped arrows with field points out to 40 yards. If I ever have a chance to hunt out west where shots can be longer, maybe I'll get a little more anal about it.
