Machete , Tone , Custom , DH , DH2 and Agent are medium flex park boards. With your 'little to zero' park activity Ill be looking for something more freeride orientated.
The DH2 is not a park board; it's an all mountain freestyle board, with the emphasis on "all mountain." Also, it's stiffer (7/10) than both the Machete (6/10) and the DH (6/10) on Ride's scale. I have a DH2.4 (superior to the regular DH2 by most accounts) that I use for groomer freeriding. But any 2010-11 DH2 probably would be an excellent choice for the OP.
