This is from the same series that billiardshot's Blomdahl video comes from, but I thought I'd mention it specifically since it's the longest run I've seen anywhere online by far.
The full match is 49:20, but if you want to skip ahead, the 18 is basically the last part of the match starting at 31:30 after Palazon misses a double-the-rail.
All i have to say is... WOW. kinda a coincedence that he missed that last shot with a variation of the same miss that his oppenent made to start his run. (not sure if that makes any sense...but.. oh well) I must be improving.. I called every one of his shots before he shot it. I dont miss much from behind a monitor
I believe I like this site better than You Tube or Google Video.
Here a couple more videos [2007] one is Final Gijon 2007,running time 72:54 and another with Dani, running time 90:29. These I will view later.
