I started out with 14's and caught fish and we still use them some. I have recently started using 16's. The biggest reason I went to 16's is to get my baits further away from my boat. Some lakes are clearer and sometimes if you're fishing shallower the sounds of the water slapping against the boat will spook fish. Nothing wrong with your set up at all if it's catching fish, a lot could be just personal preference? Good fishing to ya!
