Flow Era? First snowboard?

So, I'm a beginner 120 pounds and 5'6" looking for a board for next season. More freestyle/park oriented and more jumps over jibs but I'll probably do both as much. I'm still growing aswell, and the season's 9-10 months away. I'm very interested in the flow era 152cm as I've read it would pretty much be the best board for me now. Do y'all think I'll grow into or out of it? I can't really give a good estimate on how much I'll grow but I'm thinkin 1-3 in and around 10-15 lbs. My shoe size is a tiny smidge away from a 10 so i think i should be good in the waist width and my boot size. What do you gays think?
