I did not know Jim Greenwood did stock fitting. When he was in Augusta, KS he did an excellent job bending some stocks to measure after Mike Murphy fitted me. Jim does great work.
I have done business with JJ Perodeau and can only say great things, he is a real complete professional.
One thing you could consider as an intermediate step from the fitting is stock bending and a wood extension in order to hunt and shoot the gun a bit to see how the dimensions work.
Another consideration is that the fitting of a gun is in some respects individual to the gun, weight, balance, barrel length, and choking all play a part. I have found that similar but still different dimensions work equally well on different guns.
