Not really a chemical problem ... bad hangers can cause wrinkles, creases, and bulges, and possibly damage to sticking--that sort of thing.
You've been swatting yourself too much. Of course I saw that "nmprisons" comment was sarcastic. SF is full of crap like that, and it went over YOUR head that you thought it went over my head. I replied sanely and nicely to that comment because I thought it was the right thing to do. Maybe something you should try.
The contour shape from neck to shoulder point is more of an advantage regarding storage than the width of the flare.
Seems like a toss up on issues discussed so far. Butler wood and finish is said to be better than HP. HP has more shaping done to the wood to better support the neck and the shoulder. One puts more money and effort into the materials used to make the hanger, the other puts money and effort into the design of the product. Take your pick.
