electronic distributors - any further feedback?

My car is a 1929 Fabric Saloon which I use extensively. It does go surprisingly well though I don't know quite why as the engine is almost standard.
I have manual advance/retard and the correct timing point is now very easy to establish. Retarding the ignition slightly the engine goes 'flat', advancing it and it goes harsh. This is now clearly defined whereas before the range was much wider. I put this down to reduced timing 'scatter'.

Could I ask how you have the unit set up for the previously manual operation? Have you removed the weights-related advance function in order to keep operations as per the manual unit, or do you run with both?
Just scratching my head...
