Need some bulk vs cut advice

Like I have mentioned earlier Im going to compete in the begining of december 2005.

The thing is I have never done a real contest diet and maby I should do one now just to get a feel for it :unsure:

I would say Im around 13-14% bf now should I start a 12 week diet and aim to lose 1%bf each week the first 5 weeks and then lose as much as I can after that? Is losing 1%bf each week in the begining even a possibility?

Or would it be better if I spend all the time I have on gaining muscle mass with clean bulking until Im gonna begin my real contest prepp 25 weeks out of the competition :unsure:
