Well, I guess if its not broke don't fix it! If you are getting good drivability from Alpha-N mode, leave it alone. If you decide to try speed-density mode again you might try lowering your VE values at idle until you get a reasonably close match between target and actual AFR. I've got mine idling at a target AFR of 14.5 and I'm using a maximum of two degrees of timing trim. With these settings, I am getting a pretty smooth idle at around 800 RPM. It is a good idea to balance your stacks with a gauge (your orignal purpose for this thread). I did this and my idle quality improved quite a bit. Be sure to follow the proceedure that TWM recommends when you do this. It involves unhooking parts of the linkage and adjusting other areas of the linkage to get things right. I think that their website has a .pdf that you can download that explains how to do this. Good luck with the rest of your tune and let me know if you would like any help with that.
