In front of the string............

Actually, depends on the type of rest you shoot. If it's a shoot thru rest or flipper style rest, then it is cock feather out. For a fall away then it's cock feather up. If it's a whisker biscuit, then you need a different rest.........

Once again, just messing with ya, if it's a whicker biscuit I am not sure it matters where your cock feather is as the rest hits all the fletches anyway you turn it.
