I was a big fan of the matzuo sickle siwash hooks for a while. I put them on all of my plugs, spinners and spoons and then something changed in their process and they became too brittle. I started having breakage issues with the open eyes. They would crack when crimped, a few failed when crimping, but worse I had several fail with fish on. I was stubborn because those hooks had worked really well for me for a while, but after close to a dozen failures on fish I decided to switch out. When bending the eye open with my split ring needlenose I had close to a 70% breakage rate. The 1/0 and 2/0 seemed to be the worst I think the 3/0's were more durable, but in any case I'm done with them. I've switched back to gami siwash and I'm trying the mustad ultrapoint. I haven't used the mustad's long enough to make a conclusion, but I like the factory offset and the greater than 180 curve that should result in less fish lost. My only concern is that is might also reduce hookups. I will be waiting for the arrival of the gami sickle siwash because IMO that design is hard to beat.
