My problem now was how to cut the roach in two. My ever present trusty penknife having removed itself from my pocket. The scissors in my minimalist tackle box are short in the blade. I managed to hack the fish into two and cast the tail close in over some maggots and the head over to the edge of the sparse reeds on the far shelf. That might be dangerous as past experience (circa 1983) was that baits placed there for eels often lead to the fish running into the reedbed and becoming immovable - or, if not hooked, then the rig would snag up irretrievably.
For this session I did away with the mono link between mainline and leader. It seemed superfluous. Again I was fishing tight to the lightly set bait runner. The knotable leader is finished with a loop which goes over the link on a quick-change swivel. This is a nice simple set up. In fact coupled with 12lb mono and my 11ft 2.5lb P-2s, by simply changing the hook link, it could be used for carp, barbel or zander. A minor tweak and 15lb mono or 30lb braid would make it an even better multi-purpose set up.
Next time I shall be using my light pike drop-offs. That was the approach I used to use for eels, so I can't see why it won't still work. The rig shall be refined slightly with a heavier lead and either a run ring or large eye swivel for the lead. I might even give braid a try. One thing's for certain. I'll be making sure I have a better bait supply in future.
