So... the UIAA has 3 videos posted to their website showing a bunch of tests on various gear (ropes, cams, hexes, knots, etc.). Totally worth the 5 minutes to check them out. Follow this link.
Also... if there are any other climbers who push 15 stone or better; this link shows some interesting testing of ropes for masses larger than the UIAA standard.
Enjoy.
