Been fishing for around 40+ years now so i know quite a bit about most methods and generally do ok. Thought i would try my hand at bread punch fishing for first time and after watching several videos of the method on youtube i thought yeah seems straight forward enough, however had two fishless attempts now so either i am doing something wrong or there just aint enough roach in the canal where i am fishing. I fish the Rochdale Canal at chadderton/Middleton, average depth 4ft and very clear at the moment. Used a 0.5 gr float with olivette and droppers just touching and also just off btm, 4 and 5mm punch over a walnut size licci bread, main line 0.10 to 0.08 hook size 18. anyway had to little dips all day, any tips would be most helpful, do i need to scale down further? Notvtgectypecto give up and will continue to try and improve.
