Ray,
I don't think a yearly taste profile change is required.. Good is good year after year.
Judges palets don't change year after year. What changes yearly are judges. At Smokin in the junction I was suprised how many new faces I saw in the judges tent. I think that is your variable. If you are happy with your product stay with it, you will get what your after from contest to contest.
On another note I don't remember if it was you or Jay I talked to after judgng Sun. (I'm still not sure by sight which is which) but after I left I thought all I did was mention the bad side of the days results and I could see you might think I was just a whiner. I'm not, there were much more good (some excellent) entries and I should have focused on that instead of the poor entries. I want to be sure all the cook teams know I'm not a Debbie Downer.
My bad.
