Yes, another timing question!

I have an MSD box, but the stock distributor. I plan on checking TDC on the balancer against actual TDC in the hole of #1. Balancer could be way off if the cam wasn't installed straight up. It seems as if the car wants more initial, as the idle smooths out nicely and the vacuum increases, also. It's now a matter of controlling how much and when the mechanical advance kicks it. I'm looking at either the MP distributor or the MSD Pro Billet unit mechanical advance only. Any preferences as far as ease of adjustment??
