As they apply to traditional bows...

What is "Cast"?

What is "Stacking"?

Also, what determines how smoothly a bow will draw and shoot with minimal hand shock/recoil?

I have a hankering to grab my brother's 50# recurve he bought a few years ago then proceeded to store in his gun case and get ready for next year, so I'm doing a lot of looking around at traditional sites to learn what's what then dive in head first...
