San Manuel has STP on All-Stars midway between the high limit room and the Serrano Buffet. The best paytables (which aren't all that great) are at the $1 level for 5 or 10 play. They are: 9/5 Jacks, 9/5 DDB and 9/6 DB. Those same paytables are available for standard 5 and 10 play as well (without the extra coin bet STP feature) or on Spin.
The best play in the casino continues to be the $5/10/25 8/5 Super Aces 3-play in High Limit. You'll take about a 1% hit by instead playing the 7/5 Super Aces located on the main floor at the valet parking entrance. But at least it is available there at the more affordable 50c or $1 denomination for up to 5 play.
