Love the Roids holds. They are works of art that you want to climb on! The attention to detail is what makes these holds so special. It seems like we are always trying to find a littlle better Roid . to position with to get the sweet spot. Keeps us guessing a bit and more interesting . We use these on a 30 degree wall and they are very nice. They became favorites right away. Look forward to trying out more of the Roid sets!
