A softer flex profile makes it easier to press and do other freestyle tricks on the ground. Also for jibbing (hitting non-snow features), you don't want sharp edges that'll make you catch while sliding and potential hurt yourself. I think the Subzero comes with a 3 degree base bevel too which raises the side edges off of the snow. This helps in preventing such hangups on jibs and also makes your turning less "catchy". Good luck on your decision!
