Petronix Electronic Ignition Any Good?

Yes I put in the Flame Thrower coil in, however , when I 1st installed the Pertronix dist. I tried it with my old high output coil, so I may have damaged the Pertronix unit inside to of the dist. I am going to replace the Pertronix unit inside the dist. at this point we do not what else to try , the engine really seems like it is losing spark[ based on the way the timing light was acting] The Ignitor II , from what I just read , controls the dwell on the coil, so I am guessing maybe the Ignitor II is messing up the coil as far as the power output, I they say that either the Ignitor II works 100% or not at all.????
