Holeshots from Proline in M3 could also help as well, but I haven't run any yet to decide if the wear factor is worth it. Might be good for a qualifier and a 30 minute main or something.
Panther switches work awesome inside on clay but when the track dries out we usually switch to inside jobs in M3 compound. Both the Switches and Inside Jobs have pretty good wear characteristics if you are hooked up and easy on the trigger.
