Octagon

This is the infamous thin crack between

Maxilash

and

Vault

. It uses the same descent as

Vault

(i.e. through the rock to H & H Grunt). This is a practice in the art of combining thin tips jamming with simultaneous flaring hand jams. A good route to practice for this one is New Mutant near

Friday the 13th

.

This protects well, but use extra long runners below the roof.
