I've used my Block target for two years now. As long as the layers are vertical(up and down) arrows with field tips hardly show any wear. Broadheads are a different story,as Illini mentioned, when removing arrows with broadheads small layers of foam that have been sliced,come out also. The only time I use my Block with broadheads is on a hunting trip or after/before a hunt during the season(I have the small target and keep it in my truck 24/7 during bow season) when I want to stay tuned and make sure everything is in working order.
