This is my standard bottom rig, two versions of many. The top one is a heavy coated braid from Korda but i also use Kryston Snakebite for conditions where i want a really tough coating. The reason for the coated braid is so i can have a flexible hair with plenty of movement and if needed i can also strip some back from either the hook end or the other. If the lead is likely to bury in the silt i might strip it all back or just go over to an uncoated braid of which i have many, so choose the one you have most confidence in. The next rig is my standard fluorocarbon rig and is the one i use the most, tied with 20lb IQ from Korda. I like this particular brand as it gives me just the right amount of stiffness. The two rigs above both use a size 6 chod hook (again from Korda) and an 18mm boilie. The braid rig could just as easily use another pattern like a boilie hook but the fluorocarbon will need to be used with a chod hook if you're using a knotless knot. This is because it's a weak point and the out-turned eye on the chod hook helps negate the angle of the line through the eye lessening the chances of a break. If you want to use another pattern of hook then i suggest the excellent Palomar knot. Other hook patterns i use for bottom baits are the swept shank or curve shank hook and the boilie hook pattern. Both rigs can be adjusted to suit. The length of the hair and the length of the rig itself will affect presentation. The fluorocarbon rig is stiffer, therefore the shorter it is the stiffer it will be so it's more suited to cleaner bottoms, light silt and chod. The coated braid rig is suited to choddy conditions where it will blend in better and because it's much more supple. Both rigs use an anti-tangle sleeve to secure the figure of eight loop onto a crook at the lead, the shorter and stiffer the rig the less tangles.
