I used the same tip and put up 5- 1.5 spots on the target in diffrent places. If the shots were not within 3 inches of the 1.5" dot I disregarded it.

The lighter arrow has a smaller diameter. Your response reinforces my remark that there is a lot more that goes into it then just weight of an arrow or momentum. If I give enough examples you will just disagree with them anyway. Therefore, I'm done responding. I've proven my pont.
