I was present for one of the episodes at Mudslide. That was only my second time on the Piedra with my first time 6 years ago. It looked the same to me but I'm obviously not one to judge if its changed. We were running what I assume is the standard line with a left to right boof through the right side of the hole. The hole is backed up by a couple sievey looking rocks. My bud was using a small launch pad on the right side of the "horizon line" and a last second cross current pushed his bow into the rock on the right. It stopped him, the current turned him, and he ran the drop backwards with no speed. The hole was no place to be. After a while he swam and fortunately the current carried him out to the right. I ran the same line without hitting the rock and it went easy. I would add that my bud is a better boater than me with many years of class 5 experience. To my eye, that could be a very dangerous spot if you didn't flush right. My advice, at 800 cfs be careful not to cut it too close to the rock on the right as you approach the boof.
