I only want to hear from guys that have used both the older style cutting edge with the hoof, and the new formed ones. I plow large parking lots mainly. I like the new style, but do not know if I can justify the extra $300 over the old style when I hear of guys getting only one year out of the new style . I plan on buying the old style plus some kind of curb gaurd or extender. I have never had a problem with the "hoof", so for me that is not a factor.
