It kicks ass. I actually prefer the 106 apostles over the 98. They have the same flex pattern but because the 106 is wider, it feels more stable. Most of RMU's skis are on the stiffer side of the spectrum but the Apostles are softer compared to the rest of the selection. If you are considering the apostle 98, I would recommend the rippahs if you want a stiffer ski for hitting jumps and skiing real fast, but the apostle 98 is better for hitting rails and dicking around with presses & butters.
For skiing park, definitely get the wood core. They are much more responsive than the metal cores.
