''Which projectile do you prefer, round ball like projectiles or more oval projectiles up to pointed biconicals?

I've been doing a lot of testing with both and notice that my accuracy with the sphericals at short distances, up to a 30 meters, is a lot better than with biconicals. But the way I hold and sling spheres is different from biconicals. I release
them with the release cord in front of the retention cord using a tight grip and this gives a backspin, sidespin or underspin depending on the style, so there is an effect. Ovoids or biconicals on the other hand, I release point first by having the cords side by side upon release, so that the point is facing forward. If I sling biconicals like I sling balls (release cord in front of retention upon release) than sometimes they still fly point forward, but most of the time their yaw angles are off.

Why is my accuracy at short distances with balls better? It feels like the spheres are the most forgiving in terms of release, because they can roll in all directions. The more cilindrical the projectile becomes however, directional rolling bias is introduced. I still want to do some distance testing with backspin on spheres. But in terms of range, a well spiralled biconical (or teardrop) flies furthest, in my experience so far, and they definitely fly straightest with the best ballistic curvature. But their release seems a little harder to be accurate with, because a tangent is introduced''
