[This puzzle comes from the 2022 US Sudoku Grand Prix round. This variation again uses a double eights theme, both with two large eight shapes and a pair of given eights. I tried to have several different kinds of arrows used across the two eights, with a key question of should an eight be the sum of one or more of the arrows.]
