Replying to Best length ski 4 my height

As the title says, which ski length would be the best for my height. I'm currently 5|9 1/2 (thats five feet, nine and a half inches) and weigh 140 pounds. I'm 14 right now so I figure I've still got some growing power left in me.

My guess: I'll be 5|11 and weigh 150 pounds by the summer.

With these estimates, what ski length would be right for me? ---BTW, dont direct me towards a certain ski. Just say which length of a ski would be good for me.

Thanks
