As a commercial routesetter that has set for at least 6 gyms I have used countless holds. These holds are unique and a mainstay for any home wall or commercial gym. They are great for competitions as well as they have variably positive surfaces depending on which surface you use. Too positive? Rotate the hold and it's a whole new game. Must have! Looking forwards to getting more of your amazing (and very reasonable as far cost is concerned) holds! Thanks again Kenny! - Dr. Z
