Hi Julian,
if you want to "play around" with different setups, the Ignitech offers the most flexible solution. Also, it is by far the least costy one considering the fact that you can make up your own rotor and base-plate . You can hide it anywhere (best somewhere where water does not go to due to the Serial plug) so it does not spoil the 70's look. However, you will need to set up your own ignition curve, which is easy to do if you f.e. take some samples from the web... Have done it before for a friends RGS, worked just great.
Volker Sachse's ignition is a bolt-on device and works great, too, I am sure. However, you are limited to the curves programmed or need to send the unit in if you want to change something. Volker is very helpful on this though I was told, so - up to you.
The product with the longest experience and the most installed units in Laverdas worldwide I would say is the DMC (Moto Witt), which I installed in 3 bikes and have had 2 others where it was already installed. DMC1 in my Jota works faultlessly since over 20 years and roughly 50.000Km, DMC2 in my 1000 SFC works since roughly 12 years faultlessly (roughly 25.000Km).
there are many other systems, too, that could be adopted. I even had someone fit 2 Ignition units (!!) to a 180? Triple that were originally designed for remote controlled airplane models...
After I checked that the maximum advance was 21? though, he started thinking of maybe change to a different system...

(still could be fixed with some more base-advance maybe, as it had a base of 0?...)
so - up to you to decide now...!
