You might try a new color every year, construct a new polar diagram annually, and after ten years or so, you can just pick the color with the best polars. Keep us all posted on your progress...be sure to remove the old boottop paint before applying the new color so you don't get a build-up...that would be slow!Boot stripes are fast. Some colors are faster than others. My boot stripe is orange, and it came with the boast that way. I am sure there is a faster color, but I have not decided what it is yet. When I do, I'll repaint it.
