I'm not getting how everything the OP has said indicates a nose heavy condition. I've reread the OP's post and he says it is balanced at 2.85'' aft of LE. That point is confirmed to be the published CG by John Gilmore.
Was the model ballanced properly? Perhaps the OP should get with a more experienced modler to verify the existing ballance is as stated.
I'd never argue with verifying the facts. Speedracertrixie is quite correct that the first effort in trimming is setting the balance point and you are correct in that is should be done accurately. I simply take the OP's word that he has checked the CG and it is on the prescribed point.
