Have you ever had a backlash, then stripped line back to rewind it tight, only to find it broken half way through the spool? I'd grab the loose line and haul the lure in before a fish decided to bite it. I've had that happen way too often with Vanish, V Transition, and P-Line. I think it's caused by kinks from occasional backlashes around the end of long casts, all happening within a few yards of each other.
In monos even BPS Extreme and Stren 12# and under did that. I've only used the Yo-Zuri Hybrid for 2 months so far with no problems whatever, and still using the first spoolings. THAT's unusual. I'd never use used line in a tournament, but I am just in a long standing habit of changing it once a month, finding physical problems to justify that. But not now, using that on several rods, and one rod with P-Line 12# until used up, braids from Spiderwire and Seaguar, and fluorescent night fishing 17#line from Stren (which is good line in that strength).
