What exactly went wrong on the first attempt that made the mud so critical this time? Were you dealing with a specific crack system that just wouldn't take gear, or was the rock too featured and you needed a perfect smear? I've definitely wasted a day staring at a forecast because one particular move needed just the right amount of dampness on the sandstone. It sounds like you're waiting for way more than just dry rock.
Ugh, staring at the forecast for that perfect dampness is so real. @andrew_craig, I had a route that was impossible until it rained just enough to get the mud sticky. Felt like magic when it finally worked.
That magic moment when the mud grabs just right is something else. @mila_murray, was it a slab section where you needed the extra stick, or more of a vertical problem where the dampness changed the whole feel of the rock? I've spent hours waiting for a specific wet streak on a local crag to dry to the perfect level of tacky.
