If I'm ever stuck for ideas, sometimes it's fun to return to a combo of variants I've done before - I can find implications that I didn't see on prior use! This is one of those - in this case, I'm coming back to putting indexing lines and sum dots together.
----
Rules:
- Normal sudoku rules apply.
- Index Lines - on a dark pink index line, the digit in the Nth cell along the line (starting from the diamond) indicates the position along the line where the digit N appears. Eg: 3214 would be a valid line; the 1st digit, 3, indicates that the 3rd digit is a 1, and so on. Please note that in this puzzle, the diamond in R9C2 is attached to two different indexing lines.
- Ratio Kropki - digits separated by a black Kropki dot have a ratio of 2:1. No negative constraint.
- Sum Dots - the (2 or 4) digits surrounding a brown sum dot add up to the value in the middle of the sum dot. Repeats are allowed if available by other rules.

Very approachable index lines with some hi/lo number pairing in the middle game. Nice solving path
