RE: Primary: flat or conical ?
It depends. If your secondary diameter is small (<4.25"), a conical primary
offers better coupling. Larger diameters have better coupling by themselves
so a conical primary isn't necessary. Also depends on how much power you're
pushing. The conical will reduce the strike distance between the top load
and the primary. If you're pushing a lot of power, you'll have primary
strike problems with a conical. You may also need to use a lower coupling
with a high power coil to achieve better quench.

What's better, a flat or a conical (30°) primary ?
