Though we never actually met I call him a friend and I miss our correspondence. Jack bought his materials in quantity and when possible he purchased generic products... probably to save some money. When his supply of string material was running low he went to his usual supplier they were no longer in business (it had been that long). I was able to find a new source for his special material and that cemented our relationship.
I truly believe Jack's Gamemaster Classic is the most accurate, forgiving bow I've ever shot.
As a western hunter
Jack was head and shoulders above the rest. He'd go out and with a special lightweight camp he'd live with the animals. studying them until he knew the habits of the animal he wanted before making a move on them.
