Mike,
I hope those guys aren't on the safety committee where you work/w3tcompact/icons/smile.gif.
I think most people here would agree that rear ballast is tremendously important for stability when using a FEL, particularly on smaller compacts. I have done some calculations to estimate the c.g. (length-wise) with different loads in the bucket and different amounts of weight (or no weight) on the 3-point. Trying to combine the maximum loader lift capability with zero weight on the 3-point means that you're probably going to stand the tractor on it's nose.
The other arguments about loading up the front end too much, and about helping your rear-wheel traction (in 2wd) are valid too.
