Mazatlan 

Hey I was on the route a month ago or so and you can lower with a 60m cord barley. Knot the end of your rope and the ends just touch. Also Ixtalan you can rap from the 3rd pitch station to the ground with one 60m.

The smallest (blue) ballnut eliminates the "R" factor on this one-bomber pro through the starting crux. The "RP protected seam" at the start doesn't take very good wires, offset or otherwise, and the ones that you can manage to dick in are the smallest ones comercially available. If 10D is your limit, take 2 blue ballnuts, you'll feel better about falling on them, the crux is techy and low, with the hardest moves really only protected by the slider(s). The rack for this one is 1 set wires, cams tiny to #4, with doubles from .4 or .5 up to #3 and maybe one more #1 camalot for the top corner if you like sewing it up. Without the ballnuts this route is a leg-breaker. Heads up, and enjoy this badass pitch.

I agree, the opening super-thin crack doesn't take very trustworthy RP's. The thin crack itself is also of questionable quality and sounds brittle/hollow, so heads up! The top is really fun and totally cruiser by comparison.
