If you keep hitting the weights hard, clean up the diet real good, and do your cardio religiously... drop the alcohol, and add some juicy juice....
I'd say 25lbs. will get you to a place you might wanna hang for a while (10-12%) while you put on some SOLID gains.
After you hold on for a while, make some more gains and drop the bf another couple, two, three percent.
Keep a daily record of what you eat, what you do in your workout, and try to estimate your caloric intake along with exercise/activity output.
Get a bodyfat scale that shows progress. It may not test you at your exact levels, but it will show if you are gaining muscle, losing fat, gaining fat, gaining muscle, or worse case scenario: Gaining fat and losing muscle.
