Who is running MSD 6/AL with MSD Billet Distributor? Do you like it?

After a lot of research, I think I'm going to pull the trigger on a complete MSD 6-AL system to include their Billet, mechanical advance only distributor. I want comments from people who are running the 6-AL and/or their billet distributor. I have heard some bad things about the 6-AL, but mostly good.
I have a moderately modified 340 (approx 375 HP), 4 speed, headers , 3.55 sure grip. It currently has a 20 year old Mopar Performance Electronic Ignition (orange box) ignition has conversion. The vacuum advance has been disconnected almost from the beginning. I called Mopar Performance when I was having problems with the vacuum advance, and they said just disconnect it.
