Just for the record.....
The 6 hooks I broke were 1/0 red octopus. 1 broke on a spring king on the Frasier river on 20 lb test leader, another broke on a Skokomish king on 15 lb test, 1 broke on a Cowlitz silver on 12 lb test and the other 3 I don't specifically remember where, but they were tied on 12 to 15lb leaders. OS, I am with you, how do you break a hook? Don't know, just know that out of the 100 I bought 6 broke. Out of all the tackle components, the last one I would expect to fail would be the hook, and then I would expect it to bend out as a last resort.
Within hours of my original post on this thread, I got a e-mail from Fishead5 asking for the details of how I was fishing to get some details and offering to send me another 100 hooks. I am willing to try another 100 Visions, but it was not my intention to get anything for free, just report my experience with Vision Hooks.
