Personally, if
I were to do the motor mount again, I think I would shoot for 0 deg offset.
Just my 0.02 worth

I agree with Ed, especially if there's ANY chance you'll change the prop rotation later.  The RV-3 was nearly uncontrollable on takeoff with the wrong offset following the change from B to C redrive.  I ended up shimming the mount to get it back to zero offset, and it wasn't bad at all after that.  Of course changing the shims on the mount also means moving the front of the cowl where the spinner lines up, which is by far the worst part of changing this.  
 
Cheers,
Rusty
