My vote is to allow both the Toyo and Hoosier for Oregon Region for 2012. The mid season switch does not make sense to me. I started 2011 purchasing 2 sets of new RA-1s and phased them in through the season. They are now getting to the end of their service life, so they probably won't make it to mid 2012.
As far as STL is concerned, one could argue that it is open DOT tire. STL is a GCR Regional only class, and there is no GCR SM spec tire rule for Regionals. I posed this question last year to the Oregon Region Deputy Executive Steward, but got no answer. So I would propose that we be proactive and word our Supps to clearly state that the Oregon Region SM Spec tire rule for Regionals does not apply to SM cars running in STL. This will provide a place for folks to burn up their old tires or provide a place for folks to play the tire game.

Jim, I think your idea is the best senario for the guys running Nationals as we would be able to test the Hoosiers in the regional races. The question is whether it hurts the regional guy to have us out there with guys on Toyos.
After thinking it through for a while now it seems to me that allowing either one of the dry or rains from day one may be best way to go.
