I follow ワカ's route seen in his recent tweet. I found that you could actually swing around skipping the first hexagonal bonk, resulting in a perfect setup to also skip the ledgegrab on the second one. I didn't intend to go for it, but it just happened and I clutched the rest!

I'm unsure whether going right after getting the backpack is faster or slower though, but it was good enough to beat Mog, so it can't be too bad I guess?
