The selection of these terminal tackle takes into account the size of fish you are aiming for. Because size 4 hooks retain my bait better and are small enough to properly hook fish, that’s why I prefer to use them. Hooks smaller than size 4 are often swallowed by trout, making it challenging for anglers hoping to release their catch.

Long, thin floats are generally better for spotting bite, but they are most effective in calm waters. Round floats, on the other hand, have a bigger surface area and are therefore more difficult to drag down. However, they balance well in windy conditions.

To get the bait to the appropriate fishing depth, you must use weights on your fishing line. You could not cast your bait out if there were no weights. The required casting distance and your fishing depth will determine how much weight you use.
