Not sure about Alcoa Jonny... I started climbing in Mallory's when I was about 13 and have for the most part stuck with some form of Mallory/Opsal/Caddy pad ever since.. Sure their bulky, rattle like a mofo, and don't impress the ladies, but after trying just about every pad known to man they still remain king in my book. I still have a few pairs of original Mallorys laying around here, so I will try and dig them out and get a picture posted.Was there a third maker too? Swear I’ve seen ALCOA caddies.
