This really isn't about "two toots", rather supply chain problems. By the time Germany had enough material to send us rails, we didn't want them because the fixture was being discontinued. We did not have interest in bringing in a bunch of inventory for a light that was no longer being sold. From what I know the rails do not work on the Straton Pro. This was our choice not there's.
I don't think you have a very good perspective of the situation, while you are right we have no bearing on the engineering of their products, we basically handle everything else this side of the pond. They do listen to feedback on Labs, Firmware etc, but you are right they usually do not ask us thinks like "what features are you looking for on the Straton?" Its more like after the fact we request something and the accommodate it of possible.
Lastly, we are now accepting Straton Pro pre order and special order (depending on the model) so if you are interested please have your dealer place the order on your behalf.
