You only have problem with the power holes going from inside out because you can't see the hole. With the pathfinder you put the awl in from the outside and you can see the hole. But you don't need a pathfinder awl though a small piece of tubing would work as long as it fits in the grommet and the string fits inside the tubing. Maybe a heat shrink tube at Home Depot would work.
When you're dead you don't know you're dead. It's the same way when you're stupid.
