Ernie Frantz noticed that the South Africans were using some canvas to reinforce certain areas of their suits @ the '94 Worlds (WPC)
Ernie said, I think I'll make a whole suit out of canvas, a month or two later he had a couple that he broke out to practice with
i still have one of his "prototypes", nothing like current models but I did squat 1005 in it while training
As I recall Willie Wessels was one of the first guys to really ramp up with one - It was awesome watching Willie train
side note, Willie if you are out there you da Man!!!
so for any of you P.L. historians out there... file that info where you would like!
