You're using my Evo picture as your Avatar, but you're getting the Proto? LoL.
Anyway, the 152 is the smallest size it comes in. I'd say it's a little big for you. Nothing too bad though. Proto is fairly stiffer than the Evo so just keep that in mind.
If you choose the Evo, go with 150. I take it that you read my reviews since you have that picture so you know everything I have to say already
