Others may not see the need, but I do like the timing light I picked up that lets me read advance at higher rpms. I bought an Equus brand light a couple of years ago. Very easy to adjust it to line up timing marks at higher rpms and see the advance. My way of thinking, for right or wrong, is I'm typically driving around the 3000 rpm range, and doing shifts at higher rpms when I feel like it so measuring what the distributor is doing in that range is helpful.
