You can use blunts, or judos. I like the judos a little bit better because they impact into the tree more than blunts. Blunts will come flying backwards pretty fast, and can bend arrows more, in my opinion. But that' s with aluminum, carbons should not have any problem. Another reason I like judos, they tend to grab the grass and stuff if you miss, causing them to stop faster without bouncing down the mountain.
