If you're targeting larger fish in the bay and want to try lures, a heavier 6-10kg rod would be a good investment for cod fishing and other species.
A Shimano Sedona combo can be a good choice, but keep in mind that the reels in combo sets are often not as high-quality as standalone reels. You may want to consider buying a separate reel for your heavier rod.
For freshwater trout fishing, a 2-4kg rod would be suitable, and the Shimano Raider you mentioned earlier is still a great option. You can also look for other lightweight graphite rods with fast action that can detect bites more easily.
Don't hesitate to ask for advice from local tackle shops or experienced anglers in your area, as they can provide valuable insight and recommendations for specific locations and fish species.
