I think Nemo recommends a slightly longer pole. You may be able to get away with it, but the tent won't be as taught as possible. A good excuse to upgrade those poles!

I've found that 120cm to 130cm is the optimal range for this tent. At 120cm, the vestibules are still taught but the bottom is right at the ground. At 130cm, the tent is pitched at maximum height, providing better ventilation.
