This is in deed enlightening and astonishing.
The summary is that You can't even save much weight unless You have an older bike.
My F4S has, according to the Manual, steel flanged 310mm discs.
Swopping them to F4 1000S 310 mm alloy flanged discs is saving around 750 gr or 1,5 lbs.
This is in my eyes probably the way to go than.
Everything else seams to be weight wise pretty much in the same league.
I agree, in your case getting the F1000 rotors is the way to go.
It's kind of like having an F4 with the oem Brembo Superlight wheels, you can't get much more weight reduction even if you get BST's.
Of course you could the carbon rotors route, but they would cost almost as much as your F4 750
