The problem that no one else sent - the problem that ranked Yoshi in first place for the Summer Wars Qualifications.
He dabbed after he caught the last hold and wasn’t satisfied, but we counted it.

Grade: Red
Setter and climber: Yoshi

Moon Climbing is the final sponsor of Summer Wars!
Moon has generously provided Moon climbing bags for our prize pool. They are comfortable to use for those long approaches, durable to take any kind of battering, and well designed so you can quickly access all your gear at the crag or gym.
We’ll also be stocking a selection of Moon chalk bag at the gym. We like them for their wide opening (easy chalk access), secure drawcord closure, and practical brush holders. These are really products built by climbers, for climbers.

Everything is almost ready. We have bought some new holds and our setters will be arriving in a few days.

Grab those last tickets!

.kawamata told me how he uses chalk, so I decided to give his method a try.

It actually worked really well!!
I don’t think I would have sent this in almost one session without it.

Layer 1: Secret Stuff (0% Alcohol)
Slow to dry, but it lasts a long time.

Layer 2: Secret Stuff (80% Alcohol)
Dries much faster.

Layer 3: Gorilla Grip!
Chunky chalk.
(They have mainly 3 types, Unicorn = powder + chunks, Bam = super chunky.)

Thanks for the tips, and happy birthday, Rei! 🥳
