There are two things here. First, I probe in two or three locations. Always in the flat, there is no value to probing the point. I like to probe the thicker parts if the flat, and close to where the flat and point meet is most important. I also trim off any edges if the flat that are thinner than 1" or so. Makes for fewer burned edges.
