Ortlieb question

[petkostas]

Hello all,
Could someone shed some light, I am about to order a ortlieb rack-pack (Large size, 49 Liters), and I am also fond of some Andystrapz, the problem is which strap size should I go for?
There are 1500mm, 1250mm, 1000mm anyone have any idea?

1500mm. You can always hide the excess but can't make them longer.
