Hello Smufter and David
I'm sure there was a thread on here at one time about Ace Hooks which basically suggested they allegedly were dodgy .
When the Ace Hooks first came out my local tackle shop said they were the fastest selling hook he had ever had , but you don't seem to hear much about them now .
Is it Yonny who has professional experience with metals ? , maybe he will read this and like to comment , or send a PM to him ? .
I think it's Yonny that is testing the ESP Cryogenic Hooks .
Hope this helps .
