Lange RS130 - There's a line on the side of the clog. It's a bit more v-shaped that the stock scallop. Anyone know the estimated flex it would be if you just cut on the dotted line? Surprised they didn't mold a number in unless mine's worn off or I missed it. My googling hasn't yielded anything much beyond this old thread.
