I have been doing a bit of trotting recently and yes its a fantastic break from sitting behind static rods.
I was also chatting to a guy earlier this year who was fishing a swim on a fast river and he was also singing the praises of the tungsten tube weights saying about the strike being better…he was also convinced that they gave a better and more consistent descent to the bait as it fell through the water. I was not totally convinced but he was certainly catching a lot of fish on the drop.
