msd or mopar hei ?

the one thing i really like about msd distributors is that you can change the centrifugal curve by changing a bushing, and how fast it comes in by changing the springs. a very modular system. when you get into needing spark retard, 2 steps, boost control, go with msd. i have no doubt that don does a great job with the chrysler style boxes and distributors, i just prefer msd. you make the call. i just figured you need to hear from both sides of the fence before you make the decision.
