big C vs small C windups for forehand topspin dinks

I observed for topspin dinks different pros have different size of C motion windups. It looks like Zane, Anna Lee Waters, and Anna Bright have bigger C motions and Patriquin and Frazier have smaller C motions. I guess this is similar to backhand dinks that different pros have different styles such as Ignatowich vs Garnett. Whatbis your take on this?
