How bait behaves in running water concerns anglers more than fish. Fish will see it as an edible item and pop ups most likely with curiousity; if it smells/tases like food, it probably is. This one was was caught on a 14mm flouro popped up around two inches in a fast flowing section of the warks avon a couple of years ago. The rig putty which was balancing the pop up came off in the fight.
