Here in San Diego, Chis McIntyre is making real Gutta Percha balls. I ran into him while playing Rancho Bernado GC and he was testing three different types; all different weights and diameters. He feels confident that his balls, using the original molds, will provide a more original experience because they are made of real Gutta Percha; many of the ones on the market are imitations. He hit all 3 with a long nose driver, circa 1880, and they travelled about 180 yards.
