Going back to the Saab

1. Is a 19in rollaboard OK or should it be a 22in?

2. Which case will hold up better/longer: the PNT nylon for $149 or the PNT split leather for $179?

3. Finally, for any Mesaba pilots out there, how many 2in and 1in binders are needed?

Hopefully this will be a helpful supplement to the original post. I'll be training for the Saab soon and have the same questions.
