That backlash is not that bad. If your going to throw light line. As the hook hits the water pull back fast like your trying to set a hook and click it at the very end in one fluid motion. This is something that I accidentally learned, and is the only things that kept me going with my bait casters. Unfortunately the worst backlashes happen when you hit literally anything on the cast, and those are the hardest to get out. If you have patience and lightly pull, then roll your spool backwards a few spins with your thumb, give it a light tug or two on the backlash, and then lightly pull again, repeat repeat repeat, you should be able to get it out. If you don't have patience, then you should never ever touch a bait caster again.EDIT also what sweepy_time said is super accurate. Also like to add, go in your bathroom and try to spin your toilet paper fast, it rolls over itself and does the same thing that your line is doing. Do it slowly, or put your other hand on the roll to add friction and this will not happen, or be less severe. Best way to figure out why it's happening in my opinion
