I'll add Powder Keg @ SDC to my list. For something that is marketed as a "family coaster" this ride sure packs a nice punch. The launch is awesome, there is some nice air on the first drop, the g-forces are nice throughout the rest of the ride. The second drop provides some nice air in the back row, and the last turn is unique. I really think that Powder Keg is a VERY underrated coaster.
