Hi mate use flourocarbon put a korda sinker onto line then a 4-5 mm rubber bead onto the sinker then your hook link then another sinker with another rubber bead leave about 4 inches apart then attach your lead to the end of the line with a rubber sleeve covering the swivel i normally have the hook link about 18 -24 inches away from the lead the weight of the sinkers should keep the boilie down if not use a bit of rig putty on the top of the swivel on your hook length
