You are going to want stiffer bindings on that board. The Deltas are okay, but I'd do the SPI instead since it is stiffer with an ankle strap that has an adjustable flex.
On Rome's side, go with the Targas rather than the Boss. Same reason as above.
K2 Auto Evers are also a sick choice for the DH2.4. Those are a little pricey though.
