My experience - If you backlash it badly, it will kink the line - you know, the little pointed loop that hangs up. Guess what - THAT'S where it will break in short order. If you are fortunate enough not to backlash it, and it gets worn with abrasion & where it isn't clear anymore - pull it off the spool & turn it around. Life #2. I have 2 hooks on the fence across my back yard I pull it off onto - tie the worn end back onto the spool - and pull it hard while respooling - if you stretch it, you'll pull all the memory out of it. Round 2.
