I was just wondering how much effect an arrow wrap has on the spine and the foc. I would like to add wraps for looks and easier retrieveablity, but also to slow down just a little. Do yall think that it would be neccesary to use a heavier field point to maintain a good foc% and how much would adding the wrap affect the spine.

I did wrap a couple of practice arrows and they do hit about 3.5" to 4" low at 30yds. Would this be due to the added weight of the arrow or do i need to do a little tuning. Seems like a lot of drop just for adding an arrow wrap.
