The Metron M10 is a great choice. b4 construction, so it will hold well on the Pocono Packed Powder (See:ice), a sidecut in the low teens so it will make some nice carved turns yest can be modulated into longer turns. A turned up tail so you could bring it into teh park, but htis is its weakest trait. You can find htese in a 172 pretty readily on Ebay. The 124/74/112 ( think thats what they are, going from memory), other than the new m11 B5, are the most versatile dimensions of the Metron line.
The Nordica Enforcers would be another fine choice as is the Volkl AC3
