I have been doing Faamba missions and haved collected quite a few Hide Segments.In the 2 dozen or so i have,there are four that are not called segs but look the same.Upon examination they say they are a component to be used to make Segments.My questions are.......What are the value of these???IAnd if a certain number have to be collected to be of value,how many?Are the segments worth more or are the the hide components??Thx guys.
