Simply put, nobody can turn down the skill increase on your account. It isn't possible. I see you have moved to baitfish and I think you are on the right trail as you can get them with a really high bite rate in the right spots. Also not only are you catching something you can also use to catch other fish, but the high bite rate gives you more of a chance of your skill increasing. If you are missing bites you might even want to go down to just one rod so you have a high chance of catching each fish.
