Oh yes, Jack, you mentioned maps and highlighting features; if the Measham is still navigation by map references only, then it can help to highlight every tenth grid line so that you don't need to keep referring across to the edge of the map to plot the references. On daylight rallies I also used to highlight spot heights, as they were very often used in instructions and can often be difficult to identify when plotting, but I suspect that's not necessary for the Measham.
