According to Bowtech the Solo cam is 33.3% more efficient at throwing heavy arrows than the dual cam' s.
On the last page of the manual:
speed loss: SC - subtract 1 fps for every 3 grns added
DC - subtract 1 fps for every 2 grns added
Though the DC has blistering IBO speeds (about 20 fps faster than the SC Patriot)
If you bump your arrow weight to 450 grns - they shoot about the same speed[

]
Go real heavy and the slower IBO SC Pat would be faster.
Am I reading this correct??
Is this typical with dual cam single cam comparison??
Just food for thought if you plan on loading up a DC Pat
