I have been saying square but what I should be saying is the riser isn't running parralel or square in many cases.


Plus,on a second note,the riser squareness or parralelness(is that a word)has absolutely NOTHING to do with efficiency.


That is determined by the powerstroke,and cam design.

Now,if you go and align the powerstroke to a riser that doesn't run parallel with the power stroke,that will definately negatively affect powerstroke and efficiency.


Want to get into fourth axis yet.[]
