Opinions on PERFORMANCE DISTRIBUTOR~"DYNA MOD"~TFI???

Greetings guys-

I wanted some opinions on Performance Distributors, "DYNA MOD TFI" module and the Screamin DEMON coil? Anyone have these prducts, whatta ya think, before i buy'em. or should i just stick with MOTORCRAFT TFI & MSD coil and call it a day!
Current set up right now, Is an original motorcraft TFI module from 1991. A Ford Racing Hi-Po coil and and MSD 6A box with some FRPP 9mm wires and some NGK plugs, MSD cap and rotor

Thanks for your input,
Later Ant

MSD TFI's suck, Lots of problems from what i gathered. So iw as gonna go motorcraft-the safe bet, but figured DYNA MOD TFI and maybe there coil as well. But unsure.
