Just not enough data here to help you. Where are you going to ski? What type/brand of ski are you considering? Do you want to grow into the ski or not? There's no one simple answer to this question. You are a large guy at 245 lbs...generally you should be on a longer board 170-180 cms long...but obviously don't want be on something that is tough for you to control as you continue to develop your skills. If you provide me with a bit more data...I can provide bit more help.
