I'm getting the 9'1" board (200 pound newbie here), Its new and i'll be getting it for $440

I've been renting a 67liter board (8'6") from them. Do you think the extra 11 liters will be noticeable? Im hoping it'll make it easier to catch waves. I haven't had too much of a problem, but I would like to catch them a little earlier if possible (green waves?).
Now I'll keep practicing my pop-up...
