Loaded Northbar bottle darter in plastic, 70-80 yard cast on abu 7000 with 50lb pp.  Backed with mystery line that i haven't seen in ages.  The fish took the plug and peeled line for about 5 seconds.  I turned her for about a minutes and regained some line.  Then she took off for P-town scorching line out at a ridiculous rate.  I tightened the drag a bit more, saw the backing and thumbed the spool to prevent hitting the backing.  Pop, i reeled in the plug, broke the wolverine that i put on 3 weeks ago. 

 A few weeks ago i got a backlash and snapped off a plug and apparently it took more line than i thought.  It didnt occur to me that i needed to re-spool.

  I had 250 yards of line on top of the backing.  I figure i may have lost 30 yards a few weeks ago.  Im re-spooling today with fresh backing and 300 yards of 50 pp again, this is not going to happen again...
