Hi Fred,  B1 is .75° flat and standard loft and face angle.  Our standard face angle is .5° open.  If you move it to C1, you will lower your loft by .75°, keep the lie angle at .75 flat and the effective face angle will be 1.5° open.

Is the D3 more open than the D2 at corresponding settings?  Example, at setting A1 are both drivers open 1/2 degree?

The D3 and the D2 have the same face angles at the same settings.  Both are .5° open at the standard loft.

A1 is 0.5 open.  D1 is 1.5 open.  D4 is 0.5 closed. 

Is A4 1.5 closed?

Thanks.

A4 is effectively 1.5° closed.  If you have your chart in front of you, the top row (highest loft) is 1.5° closed, the second row below is .5° closed, the third row is .5° open and the bottom row is 1.5° open.  Please keep in mind that your lie angle will affect the direction more than the face angle.  So, going from left to right on your chart - the first column on the left is 1.5° upright lie, the second column is .75° upright lie, the third column is the standard lie and the column on the right is .75° flat lie angle. 

Thanks for the clarification.  I like a little closure to minimize side spin, so I'll probably not try D1 (LH).  I was getting too much pull on both B2 and C3, but A1 did straighten that out.
