Yes... We have access to a three wheel machine that throws a rise, drop, curve, screw, and combos. Agree with your assessment of a rise dropping less. I've noticed in this debate there is one camp focused on altitude changes and whether they happen (usually saying no) and another focused on trajectory differences (rise causing the illusion of rising because spin reduces the impact of gravity). That difference in perspective is usually good for a 50 post thread. While I tend toward the trajectory camp (spin can't overcome gravity but appears like it can), it is interesting to note that altitude does sometimes rise due to trajectory at release (hand low, ball headed higher) aided by spin which reduces gravity induced drop (and therefore pitch finishing at the numbers or higher in many cases).Everything I have read says that women (and maybe men too) do not throw hard enough, with enough spin, to allow the ball to go above the plane the ball would travel without gravity, so in that sense they do not "rise". Riseballs work because they drop (from that plane I mentioned) less than fastballs and look enough like fastballs to mess with the brain's ability to extrapolate from previous data. On that note, do they have riseball machines for softball like they do for sliders,curves etc in baseball?
