I added a few sets of these to my 35 degree system board. At first they felt positive and even too easy. Not the case as once my core got tired I was falling off, even with the hold set at the most positive position. It was easy to get them adjusted just right with the markings on the side. As I suck less at grabbing these holds I can turn them to make em slopier. Value! The texture is perfect and doesn’t destroy my skin when peeling off. 5 stars
