I’m the same with my lures swapping and changing, always afraid I’m using the wrong one for conditions etc. Recently something changed, I found a lure that I feel 110% confident with. A lure that gives me options and reacts differently when it comes to rigs and a lure that I feel I connect with and one that I can work effectively.
The realistic shads Gudgeon 7cm lure is my current go-to lure without fail, if I had to choose one lure for life it would be this lure. The lure is super soft which is important to me as I believe the fish hold onto it that split second longer allowing me to set the hook firmly.
It is also important as my current go to rig is to fish it weedless style on a 2-4g Cheb head with a size 2 offset worm hook as the local canal can be quite leafy and have lots of debris on the bottom. The action of the lure is hugely influenced by the weight, if the waters cooler and I feel the fish are a little more sluggish I’ll cast and retrieve super slowly with small twitches. This tames the action and I feel better represents the action of baitfish in cold water.
