Although the 26 might suit you best at the moment, I think getting a 30 would be a wiser choice... you'd have plenty of room for your things and you'd grow into the bag.
^^^^ Yup, I totally agree.
I suggest to get the 30 as well because it will hold more and I remember when I was 16 years old I actually carried more stuff then I do now at 23 years old.
