So I have a good set of yellow vegas, duro 40-42, that handle very well in the heat/dry slick/ dusty track conditions. As fall hits the new evening weather is going to a cool/ dewy/ tacky track. I have a second set of yellows that duro around 32-35, I set these up intentionally for the wetter, cooler weather. My question is, during the week, do I use a the normal low bite mild prep, and then add a more aggressive prep at the track, OR, do I add the more aggressive through the week?
