I work at the gander mountian in the achery departmentaround my area. The answer is that youdidnt get the older set of shafts.The arrows with the camo are called maxima hunters youhave theregular maximas,allthe maxima huntersmean is that their is camo on the front half of the shaft making it weight forward. Themaxima huntersare 1 to 2 grains per inch heavier so they will shot different than the regular maximas. I would keep the regular ones since there are lighter. So there is a difference in weight but thats it.
