I am trying to learn the proper way to fish with grasshoppers. I have been using a #8 baitholder hook and hooking them through the "collar" but they seem to die rather quickly! Is this normal or is there a better way to thread them on the hook? I'm just curious as how others use them and weather they are best on the surface or underwater? Down at my fishing hole there are some walleye swirling in the shallows and can't seem to get them interested in anything. Can anyone help me out?
