Personally I would like to have the best of both worlds. Mags have the advantage of their own electical system so they don't rely on the battery/alternator. Electronic ignition has the advantage of being able to advance the timing at higher RPMs and also the advantage of a much stonger spark. You can get all of these advantages rolled into one if you use the new P-mags, Slick LASAR, or the other one that I can't remember the name of right now. Of course you will pay a lot more, but you will have more power and better fuel economy also.
While we are on the subect, one of the greatest advantages of an electronic system is the ability to advance the timing at higher RPMs. Mags typically fire at about 25 degrees BTDC. The engine will produce more power and be much more efficient at cruise RPM if the mag fired sooner, only problem is that it would be to much advance at lower RPM and it would not idle well. The 25 degrees is a compromise and why you don't get a nice smooth idle and easy starts on an aircraft engine and don't get the full power and economy at higher power.

Only in aviation can you find such strange things... That is exactly the way outs is set up because I wanted the best of both. Each has it's advantages and disadvantages. This gives me the best that I can get under the circumstances.
