Parity Party V

Normal Sudoku rules apply. In addition, a colored stripe may not contain repeated digits.

Special rules of Parity Party: A number at the edge of the grid indicates the sum of cells encountered when moving through the grid from that vantage point, UP TO AND INCLUDING the first odd or first even digit. For example, the 15 at the top of column 9 could indicate something like 7-8, 8-7, 1-3-5-6 or 2-6-4-3 (among others)... but not 1-2-3-4-5 or 2-6-3-4 etc. That is, the parity of the farthest digit must deviate from that of the others.

Note: If the clue is less than 10, it might simply indicate the value of the first cell. That is to say, you could be adding up zero odd and one even number, or vice versa.

For this puzzle, 2 Parity Party clues are also provided for each of the stripes (imagining each one as a straight line of digits) For example, one stripe has a Parity Party sum of 9 from one end and 30 from the other. However, the puzzler must figure out which pair of clues goes with which stripe (and from which end each clue applies)!
