We decided to see if we could make a very similar and Basic Ellipse shape but make one half only just usable and the other side completely unusable. We added a few shapes and sizes to complement the whole Basics offering. Using the same component part as all the other Basic families that have had the majority of the work and technical engineering as in the rest of these macro holds. This part creates no edge where the macro joins the climbing wall, so the climber is forced to use the part of the hold that the route setters want to insist the climber has to.
