Ideally, shot your pole float using a piosipombo shoting device. Even for running water i find it is best to use for example, 4 No.4 shot, rather than a BB for your bulk, this allows you to be more diverse in your shotting pattern, and lets you move it around, or if needed split it, dependant on the water you are fishing. Incorporate at least three or even four No. 8, or 10;s on your rig as droppers.
