yes i know about the flatlines, what i meant was i have limited physics knowlege, i know enough about paintball (i've been researching and such for 2 years....mostly on low ends and pumpers tho) to know what products do what. the things you mention are used to create spin, and due to the spin, it would create lift and keep the ball along a straight trajectory. what i''m saying is create seams on the ball and have the back of the ball heavier than the front. conventional loaders and equipment would still work, the seams would disrupt SOME of the vortex shedding effect, and the weight bias will keep the seams facing the right direction.
