Well I would go with the Kreation for park but that has a 90 flex to it the SAS 110 sensor 3 has a 110 flex. Higher the number on a flex means the boot is stiffer. Anyway, if you're skiing park my advice would be the kreation but since everyone is different its hard to say. The SAS 110 boot seems good for all around but, some people like really soft boots for park some like stiffer boots. I have Rossignol Scratch boots from 2008 I love them there a 85/95 flex meaning i can adjust the stiffness with a allen key. But to choose for park skiing i would go the Salomon Kreation with the 90 flex because i like soft boots for park. In the end dude the best thing you can do is go with is your choice since I don't know if you like soft or stiffer boots, or if you ski backcountry or park. Another thing is I can't find the width the last of the Kreation but the SAS width or fit is medium 100mm.
