MSD digital E-Curve? who's got one?

Right now on my car I have an MSD 6AL, blaster 2 coil, and the MSD billet distributor with no vacuum advance. I would like to change it out to the MSD digital E-Curve distributor, it has vacuum advance and this is mainly a street car that will see the track every couple weeks.The previous owner of my car put the MSD in it, and it seems to run good but shakey at idle, I'm thinking to just change it out to a e-curve distributor with vacuum advance and clean up the engine bay a little bit. Motor is a built 360, 9.5:1 compression, J heads, comp268 cam, headers, holley 750 carb, edlebrock air gap intake. Any of you guys got advice for me? does this seem like the right thing to do? anyone have the e-curve distributor? how do you like it?
