Regarding the foam rollers, my wife found the very same roller in a 3 pack at the local dollar store. They seem to work as well as the ones from Can. Tire, and they have the one straight edge, not rounded on both. I found a big difference in roller lines with the straight, doesn't leave as much on overlap.

I want to die like my Grampa, peacefully, in his sleep. Not screaming in terror like his passengers.
