Hi Dan,

"I" would always use a flat secondary.  There is little reason to use a 
cone unless one were really starved for coupling.  Even then, best just to 
make a bigger flat than go to all the work making a cone.  Some people 
think cones look cooler though ;-))

The coupling can be calculated using Mark R's classic program at:

If you get between 0.10 and 0.20 you are there.

Cheers,

         Terry
