I purchased three 125g 4-blade broadheads which were very economically priced. They are sharp and spun true. What I really like about them is they are 100g heads with a removable brass color. I think this is a great idea. So I can use them as either 100g or 125g broadheads without buying separate broadheads as with other makers. I don't know why other broadhead makers don't use this method other than they may sell fewer heads.
