Mini Belicoso, is just a shorter Belicoso. Usually has the traditional robusto length. (Altadis has many cigars in this size). Beli is a little bit different from the Torp though.
Torbusto, just think of it like a perfecto (that has the widened body at the center), but doesn't have the perfecto foot. Take a Torano Signature perfeto, AF Short Story, or Cuaba, clip about half an inch of the foot off, you've got yourself a Torbusto. Altadis and General has cigars this size.
