No need for wire on kings at all. I dont use wire on tailor or bonito either and they have decent teeth (for sydney fish anyway). Dont know why it bent, locked up when fishing for kings after a hookup. Not sure if faulty or servicing issue. If casting braid , the deep spool is not good either, but will work fine with mono. I swapped mine for a spheros and it hasnt missed a beat.
Mine was a 850ssm, I much prefer the old model. Spare spools for the penn are $90-110, and considering you can buy a new reel for $100 now or so for the 850ssm.
