The pin pull isn't too hard, but I wouldn't wire it for a tripwire application. As a booby trap, the best bet is to hold the spoon down with something (say push it into a cup) and use the tripwire to pull the device out of the cup. You would want to use some sort of ingenuity to let the wire pull free of the device instead of having it drag around everywhere when the wire is pulled. Tying off directly to the grenade would probably have the grenade getting hoofed into the bushes if a runner hits the wire fast.
Ideally you'd want the grenade to stay close to where you originally set it.
i never thought of the cup idea. thats a great idea, let the cup go flying with the trip wire and anchor the device. wow simple but very affective at the field i play at where a old cup on the ground is not out of place.
