Sporasub's wishbone with rotating sphere for circular slings, these wishbones, featuring a bow in 2 mm steel thread, set themselves apart from the classic sphere wishbones as they can be quickly removed without having to untie the slings. These wishbones therefore allow for sling substitution while fishing, or adding another sling, or changing the bow, in an easy and simple way. The rotating spheres, moreover, facilitate the rotation of the slings, limiting the possibility that the spheres unscrewing themselves. The wishbones are supplied in packages with 2 bows, one universal with a U-shape and on V-shaped bow that is specifically designed for America shafts.
