All my bait casters are so tuned, you can virtually cast and lay the rod down in the middle of the cast and it won't birdnest. But, if you accidentally hit something during your back cast, like your back-seater's rod, look out! Mother of all bird nests. There is a trick to getting them though. It works most of the time.I learned to cast and fish with a baitcasting reel as a boy back in the mid-1960s. Two things I learned, one, the term "birds' nest" has more than one meaning, and two, the kids with the spincasting reels had more time to fish because they weren't untangling "birds' nests".
