What route did you use to earn the Stunt Superstar award in Burnout Paradise?

The Stunt Superstar Paradise Award in Burnout Paradise requires you to get a x40 multiplier in a stunt run. I'm looking for suggestions from those who've gotten it. Which stunt run did you use and what was your route?

Choose a stunt run in the Downtown area of the map. The key is you don't have to worry about the time limit on a stunt run as the stunt run will continue even after the time runs out as long as you keep the little countdown circle going and don't crash! The countdown circle is kept going by performing stunts or more importantly a quick boost. So all you have to do when the countdown circle is about to run out is briefly boost and establish a route through Paradise City that allows you to perform a decent number of jumps and billboard smashes. There is a good amount around the Wildcats stadium area. If you need some more, head west down the Southbay Expressway and then up and into the quarry. Good luck!

I like to start just north of the Wildcats stadium, an dhead up the scaffolding on the left heading south, then round the back of the stadium and up the ramps here. When you come to the end and pop out onto the dual carriageway quickly go up the steps of the building on the north side and a hairpin to drop out through a billboard.

Then take the ramp over the water to get onto the South Bay Expressway. Just before the bridge turn around and use all the jumps in the dockyard. Back around onto the expressway and over the bridge this time, using the jumps.

Head off to the right and drift all the way to the top of the dam and get to the main entrance to the quarry and use the half ramp down into the quarry. Use a couple of jumps in there and come back out the main entrance.

Use the ramp to the west of the dam to head back down and head off past the dirt track onto south mountain drive. Loads of stunts all the way round until the end of north mountain drive and you should have your x40 multiplier by then.

The key is little dabs of boost when your circle is almost gone.
