Here are puzzles 10 to 14, with explanations by the individual constructors. Many thanks from Simon & Mark to all the people involved:
Duality 10: Clogged Arteries by grkles
Normal sudoku rules apply. Each clue outside the grid is both a sandwich clue and a little killer clue.
Sandwich: Clues outside the grid give the sum of the digits between the 1 and the 9 (exclusive) in their row or column.
Little Killer: Clues outside the grid give the sum of the digits along the indicated diagonals. Digits along these diagonals may repeat (if allowed by other rules).

Duality 12: Slopes by Xenonetix
Normal sudoku rules apply.
Arrows indicate both X-Lockout Lines & X-German Whisper Lines, where the first seen digit in the respective column or diagonal is the length of a straight line matching both of these constraints (of length 2 or more), starting at that digit.
Lockout Lines have diamonds at each end which differ by at least 4, and digits along the lines in between (if any) fall outside of the diamond digit range.
Adjacent digits along German Whispers differ by at least 5.
