How about a Lysander or a Storch, something small, slow, and carries only ONE paratroop.
How many times have you dropped on a field only to have ONE troop shot away? How many times has there been only ONE troop required to finish it off and then you have to wait for another C47 and the entire mission is lost?
Well bring one (or two, for the cautious amongst us) of these along with as backup and VIOLA your mission is saved!
Like I said just a wacky thought.
