The fast-action rods are often very sensitive and register every single bite. The rod bends mostly at the upper part of the tip and is very responsive with a quick snap back. These rods are very good for a powerful hook set and will work very well with single hooks; anything from finesse fishing creature baits and worms to standard, mid, and larger traditional jigs. A fast heavy action rod is also ideal when fishing areas with a lot of vegetation to pull your lures out of the grass or pull a fish out.
Moderate/Medium-action and slow-action rods have a deeper bend through of all the rods in general. Therefore, they give you more versatility overall. Medium-action and slow-action rods work well with both single hooks and trebles. A broad spectrum between everything from smaller fish to the big ones. Usually, the medium action rods bend from the top of the tip to the middle of the rod while the slow rods are quite soft and bend starting from the lower third of the rod.
Moderate/Medium-action rod provides good casting abilities and a good hook-set rating. For the long casts, smaller lures, and fighting even the smallest species (for example Perch), a slow (light) action rod can be great. However, the hookset capacity is a bit lower compared to a fast or medium-fast rod. But as soon as you have set that hook, fighting the fish, and keeping that tension will be much easier.
