I agree with Li and Pistonslap here. I have ridden with Jules a few times as well and it has always been a great ride!
I think his rides are so nice and people are having such a good time that they start riding out of their capabilities, and then things go wrong. People need to ride their own ride, Jules is very fast, but there is no need to try and stay with him, ride your own ride.
I remember the Parys ride where Leon broke his leg, on the way back from Parys, Jules, myself, Splash and the guy on the 640 (Matthew ??) were klapping it at some crazy speeds, as soon as I started to get uncomfortable I just slowed down a bit, no problems, everyone gets together again eventually.
So Jules, I cannot wait for the next ride!!! - Noobies welcome!!
ps, when Jules advertised this ride, he indicated that it will be fast.
