These holds are very comfortable and have a nicely shaped lip that's easy on your fingers. I love putting these on my volumes because it allows me to grab them with my hands oriented in a way where my palms aren't just facing the wall section. Basically, think of it as grabbing these holds like you were going to shake hands with someone (palms facing left or right or even up as an under cling). For all of these options, these holds are great. They are the perfect balance between a large jug and a comfortable incut crimp. I think this would be a great set to put on a kid's wall to add a little challenge.
