Here's the set-up I ran yesterday at our Oswestry regional. The track started off damp and slippery and gradually improved through to fully dry. The track was a good mixture of astro and undulating grass.

Although the sheet is from Stotfold the week before, I found the same set-up ran extremely well at Oswestry too. The only omission on the sheet is the front piston and this should be AE#2's.
