i need an overall opinion on a msd 6a

I run the 6a. I don't race or shift often at overly high RPMs. Even though I really wanted the 6al I have found for the price it's an excellent piece of gear. I have had no problems at all with it!

Great for instant starting -
Good for improved gas milage..(less waste, complete burn)...depending how ya drive.
and ya..I'm not afraid to say they look kind of cool..
