This and volume 2 are pretty good, but they are hard to learn alone. Most of the content involves 2 people. So it is hard to practice alone. All and all vol. 1 and 2 are pretty good.

This shuko works great, however they do limit thumb movement and I always need 2 people to get them on. I also recommend wearing gloves while using these. They dig into my hand while climbing. They are best when used WITH the Ashikos, or foot claws. This is because sometimes you will have the shukos to use as hand holds but it makes it difficult to climb without footholds. Hand and Foot Claws go together!
