All colors and thickness react differently even if the latex is same thickness but different color... Over time the way you present your air can change across the call. I use to could run a V or ghost cut with pride. Now sounds like a wood rasp running across a board! Now I have to use a batwing or a combo cut on the left side... But a total different sound. I use to run high tension calls thinking it would give me a better front but now I run more of a loose stretch for myself..
