From what I understand your problem is with the CDI box. If so, I would use the Ignitec. It’s just plug and play. Installing the Rae-san w/o removing the engine rear cover still leaves you relying on a less-than-new stator. And it’s no picnic to install even with the bottle out. Doable, but cumbersome. I’d go Ignitec then consider Rae-San if and when the stator or a pick-up coil goes bad. The RS will eliminate the need for the pickup coils, but it seems that yours are now working. Old, but that does not necessarily mean that they will fail any time soon. My guess is that there are many factors besides age that cause them to fail. Ignitec has had lots of satisfied users over the years who are using the old pickups. Plus the Rae-San technology hasn’t been around long enough to establish long-term reliability and the units have been known to fail.
