I don't mind paying for FSBUILD Navigraph navdata updates (I've got a subscription with Navigraph anyway, as probably most people who fly complex addon aircraft in MSFS do).
Most important thing is that once the task of doing navdata has been offloaded to Navigraph, we can expect more complete (SID, STARs) navdata on a regular basis.
I use FSC9 at the moment because of the FSBUILD navdata issue, but I'd like to return to FSBUILD asap. FSBUILD just sits better with me, and I don't make use of the FSC9 functionality that is unrelated to flight planning.
So ... keep the FSBUILD+Navigraph thing rolling!
Looking forward to the first FSBUILD Navigraph cycle ...
