I would do the starter conversion before changing from points. The starter draws alot of current and often this limits power to the dizzy making a hard starting engine even harder to start. The gemini starter is better from this point.
Bad habits in wet weather (for me) have always been the other electrical connections in the engine bay. Sure, the spark goes out but look at all the dodgy connectors BMC used

I can hose the dizzy and the engine keeps running with points.
Electronic is good for high compression, high revving engines, using it as an excuse for std engines is a bit of a sales pitch me thinks
