Nice article, Lee. I was interested in the size of baits you use, 20-40mm. I fished the Trent just upstream last summer. My baits were either 14mm pellets or two 10mm boilies. They didn't seem to have much trouble locating them in the dark, although I was also using cage feeders with a pellet-based groundbait. I only use a few freebies in the mix, the idea being that my baits are the only substantial food items they encounter after homing in on the "signal" from the feeder. One thing I will be trying though at the back end of this season is the boilie/paste wrap combination. On the subject of "carbelling", I admit that the Trent lends itself to such an approach. However, whilst I fish two rods, I prefer the anonimity and security (!) of isotopes and baitrunners for my bite indication. I also note in your CAT article that you fished the session in question with three rods. I had two barbel on at once in a session last summer, and have similarly "doubled up" with carp and pike in the past. I managed to cope on each of those occasions. However, I would have thought that fishing three rods for barbel, particularly when the fish were "on", was asking for trouble?
