I have been using the Krill Wafters for two years now and since the first day Iput one on the rig i have never looked back. I use these on my favoured alt D rig and they work perfectly. With the stiffness of the fox illusion hook-link and the perfectly balanced wafter they slowly sink to the bottom with a straight rig.
They hover perfectly, just over the hook, so the don’t look intrusive when carp enter the area. I have caught some wiley carp from Smiths pool using this bait. If you haven’t tried them yet then you are certainly missing a trick.
