Well sometimes a story has a strange twist. I had prepared the ordering process a few times, but to to software errors (subsidised company purchase). I had to request a new quote/offer all over again. This got me reading and thinking this all over again. I finally decide to do a testdrive of a Stromer ST3 to confirm the choice for the supercharger. This turned out differently. The speed, stability, build quality as well as the contacts with the dealer made me switch to the ST3. I would have been happy with the supercharger, but for the purpose of the 50 km commute the ST3 would be the best choice. This one is now in the ordering process and is already reserved (stock). So I hope to be riding it before the end of april.
