Just googling around…I don’t know of any specific resources, hope this helps anyway.

point 3.
Also… and I’m not inventing the idea but I can’t remember seeing it - a free weight exercise stresses the entire body as a supporting mechanism.

This is very true. Also, the type of machine matters as some equipment is better then others, and also wheter you would perform compound or isolation movement.
I would say that doing machine Squats, Rows and Presses is far better than doing Curls, Kickbacks, and Flyes with free weights.
But, I also believe that machines are not neccessary and that you can reach your goals, whether BB or strenght with free weights only.
Check “The Evil Scot” by Alwyn Cosgrove, I think he mentioned something about machines (most likely negative). Also go to Joe DeFranco’s website, he bashes H.I.T and machines pretty good.
