Fishing on deep (3-5 m @13 m pole) Northern rivers with strong flow. Having an issue getting proper bites on flat float. Mainly fishing for silvers and bream up to 2kg. I made my rigs according flat float introducing Will Raison's video where 15g rig consist of around 30 cm hooklenght, first bulk around 0.4g (no. 8s), 20 cm cap, second bulk of no. 8s (around 0.6 g), 20cm cap and 14g olivette. I suspect that small bulks are too light to get nice positive bites. I fish from the bottom (20 cm overdepth). Secondly, is there even any benefit using numerous no. 8s or maybe should i use just single 0.5-2 g weights instead since in my region it's legal? I wonder if rig with heavier droppers: 1.5 g, 20cm, 3.5 g , 20 cm and 10g bulk on 15 lollipop would give better results or it will rather cause more misses? I got some improvement when replaced hooklenght with shorter one (20 cm) but i still feel there's room to improve.
