I' d like to also reply here because others might be intrested. Think of tuning your dual cam bow as you would a single, just work with one cable! For me it is very easy to match the cam synchronization with just 1/2 to 2 twists of ONE cable. You may notice that your groups will be better veritcaly at longer distances and broadhead tuning may be easier. The valley on the BKII cams is very short and I believe that cam sync, if a little off dosen' t make much difference in accuracy. It does make quiet a difference in the way the valley feels at full draw IMO. I just get the cams to where they hit the wall at the same moment and go shoot! Once set, you may never have to do it again. I' m getting over 83 foot pounds of K.E. with my 71 pound Pat DC You should too
