Addition # 11 - Cut in refractive indexes 1.54 to 2.14 with no changes. This is designed for moderately saturated watermelon rough. Notice the large reflector mains. This also works well in about any rough. Note: The girdle can be cut in first and the P1 cut to meet so that center point is not needed and it saves rough.
