Hi Mark,
I also used these hooks and made some impression.
First, I was really happy to see the maker emphasizing barbless trebles. Many japanese makers are talking about environment, but I am happy to see real steps to prove their words. Though I understand that they have to think of business...
I liked the curve of these hooks very much though from the beginning I had some doubts in it. I thought that the sharp corner in the bottom of the curve will stop the thick lip of GT from penetrating further along the wire. This might put excessive leverage on the wire to bend it out. But having used it and seen how the hook sits inside the GT's mouth, I changed my opinion to very positive. The hook sits very good and it is really hard to take it out. I think that this might be a great advantage when they appear on the market in barbless version. Of course, we should continue testing and see the results further.
I also liked their ability to stay sharp after fish. Very good so far.
They have black and silver color. Silver is not bad, but blacks corrode faster. Though I heard that from new year the maker will use new coating for blacks, so this problem will be eliminated.
As for the strengh, one 6.5/0 broke at high drag. I think this is a problem of most hooks now. But Intense is very responsive. They said they will work about baking technology to improve the strengh of their hooks. I think that we have very good hook maker potentially.
