Having received rave reviews, I knew I had to give these a go. I chose the Gripper versions in sizes 4 and 5 for my favourite pop-up rig. Despite being a relatively thick wire, they are unbelievably sharp out of the packet. I like how they balance nicely with a pop-up and a small split shot. I haven’t lost a fish on them yet, which to my mind is perfect. I look forward to using the Cryogens for the foreseeable future.
