Does this include the option to run Intermidiates or Full Wets? If both, will we be required to run both compounds as in the dry rounds? Could be interesting if we do need to run both from a strategy perspective... Additionally, when running both Racing Soft & Hard we can't disallow the use of Mediums (to my knowledge) if someone were to accidentally select Mediums when pitting what is the penalty/course of action required? No penalty as long as they pit the following lap to change compound back (which is penalty enough)? EDIT: Ninja'd by @Xtr3meNZer after walking away for a few minutes before posting...
You can run either intermediate or full wets in the wet round but can't mix. If someone runs mediums in the other rounds they will be disqualified unless as you say they pit after 1 lap and take them off.
When we ran there in the wet last season in the Beetle, I found you lost out more than anything else when you went out there because of the double hit of stopping and the getting going again on the wet painted surface. Best to avoid it.
