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

I've been running that distributor and a pre-digital 6AL box for over ten years and it has worked flawlessly. I started to get the rust and took to a quick spray with CRC56 once a year and that seemed to tame it. I do wish they made that distributor with vacuum advance. It would mean more advance when cruising and when not under load and that would translate to better gas mileage and a more complete burn with engine longevity value.
