I only needed to use a naked pair, a unique rectangle, and singles.

After the naked pair (78) r25c7 => - 7 r18c7 you get to here.

A length 4 XY chain => - 2 r7c2 and solves the puzzle in singles. I've also indicated Jason's UR in the cells marked * which => - 49 r8c3 and also solves in singles. A number of other 4 Strong link chains also solve.
