Forget Ian's advice..
On a hill like that it's only going to wind up drivers, who in turn will try something stupid however you ride up the hill, secondary, primary or wobbling all over the bleeding place.
It's best not put your self in that situation where that can happen.
For piece of mind find a back route through quieter streets. It may take a little longer and be a bit convoluted but it's worth it for your piece of mind.
