What were you assuming for the following values?:

BPS (breaks per second, I get about 312 for your set up, P=0.5*BPS*Cp*Vp^2,
using Cp=16nF, Vp=6kv*sqrt(2), and P=30mA*6kV)

TK (thermal dissipation const for capacitors), I used 40°C/W

Rpri, (primary circuit resistance) I used 3 Ohms

This gives me 5 x 7 caps.

Good RF grounding of the coil will help. I (accidentally) ran my coil
without a ground once, there were major arcs and sparks between windings of
the primary - indicating lots of stress on the primary cct.

Plus, don't set your (primary not protection) spark gaps too wide, 2.2mm
*total* is good for about 8.5kVp (6kVrms).
