Thanks for the comments guys, makes me all warm inside!
Yes, the R6 was fantastic. It was so small, light and flickable it was a complete joy to ride and allowed me to take huge liberties. On track it ruled (for me) and on top end power leaves my current RSV behind. It's actually about 7hp down on the Mille, but so much lighter with a far smaller frontal area so outpulls it in the real world.
The chain snapped out of Druids- I felt it go past my boot and it destroyed the hugger and chain guard with minor marks to swingarm and engine cases.
I was very, very lucky as it could've cut the engine, locked the wheel or cut through some nice fleshy bits of body.
