Trouble with the HOH is that most are all now "pre-oiled". They tend to break down and get fairly sloppy pretty fast. The pro-preferred do not come pre-oiled and are a higher quality leather. The HOH is most certainly less expensive.
If you can find a HOH model that is NOT pre-oiled it would be a great buy. If you can find a HOH that is made in the USA, best buy still-there are a few still floating around, but very tough to still find. Try Ballgloves.com or call Rawlings directly.
