I have a B800, though just the vario, without the Borgelt GPS, GCD and Dynamis. I control the settings on the B800 via the flight computer, bugs, ballast and Mcready,
Dynamis sounds great, but at $5000aud + is not cheap, maybe one day.
I’ve been wondering the same thing myself, though my recent flights with the new B800 have been satisfyingly fast, so there’s that.
