Duplicate line removal matching some columns only

I'm looking to remove duplicate rows from a CSV file with a twist.

The first row is a header.
There are 31 columns. I want to remove duplicates when the first 29 rows are identical ignoring row 30 and 31 BUT the duplicate that is kept should have the shortest total character length in rows 30 and 31 combined.
Col 31 can contain commas that are not delimiters (quoted)

Example
col1,col2,col2,...,col29,col30,"col31, may have some commas in it, but they are within quotes"
