County uses new danage blocks plus bungee in garden hose.Old danage cubes and a couple of bungee cords is a good start.
I thought so too - until I tried it. Even my 43# recurve punched arrows through (this is with a homemade layered cardboard boss - it looked like the layered foam bosses, with the cardboard +/- 8" deep). I found, also, that the carpet tiles would split, which I was worried would damage the carbon arrows when drawing arrows.Carpet tiles should work if they are hung behind.
