Hi Daniel,

The angle will affect the coupling.  You can run your coil design 
thru JAVATC and it will tell you the coupling and if too high, you 
can lower the primary (or raise the secondary).  I've built a 
inverted conical primary as well for a smaller coil and it worked 
just fine.  The inclination angle was 30 degrees.  Since you have it 
built, it would just try it and see what happens and adjust 
accordingly.  Most dont bother with these complicated primaries since 
it is still possible to get too much coupling with flat 
primaries.  Secondary to primary breakdown and racing arcs are the 
problems you may have to deal with and the relative height between 
primary and secondary is what you have to fix them.
