Tom — I haven’t done the math, but they’re about as close to the 3:1 “ideal” as we can find today, along with Tusker Concord, Grizzly and STOS gets close. Could be others I’m unaware of. All the heads named above, I have tested and killed game with and come highly recommended. I sound like a hiccup here, but imho, all things considered, the BB is best head for the money, Concord the cheapest great head, and the ABS Ashby the best-built head available. Only thing keeping the El Grande off that list is their relative dullness out of the box.
