I'll nominate both courses at Olympia Fields. The South probably has more uphill holes out of the two, with 6, 7, 9, 12, 16 and 18 being the standouts. On the North 3, 13, 14 and 17 are a worth grouping.
Beverly has a few noteworthy additions, including 5, 7 and 16 and although a less dramatic elevation change the 14th.
The best uphill hole in Chicago might be the 8th at Skokie.
