Calibration, by James Sinclair
Normal sudoku rules apply, and all clues are standard.
Arrows: the sum of the digits along an arrow is equal to the digit in the connected circle, and these digits can repeat if allowed by other rules.
Renban lines: purple lines contain a non-repeating set of consecutive digits in any order.
Digits in cells separated by an X sum to 10.
Digits in cells with a shaded square must be even.

Wow, this was lovely and smooth! I haven't been so impressed by an approachable variant sudoku in a long time.

Tough break-in, but then it flowed nicely. Great puzzle. Glad I didn't give up on it when I was stuck on the break-in.
