we have been using the Jinkai, mostly 100# and some 130. Rarely have break offs. Sounds like the strike drag is a little heavy. Momoi is definitely good stuff, use it for all mainline with no problems so far. I troll nearly all 50's, an occasional 30 and run a 70 or 80 for any wwb stuff due to what we run back there. We don't get a lot of 100# game fish down here so maybe thats the difference, but we have caught plenty of sail and other stuff - just have to be careful. About the only loss I have regularly is a wahoo cutoff, and 200# anything ain't stopping that either. I'll set my strike at 12-15#, but rarely have it up to that while trolling - its always pulled back to "what feels right".
We fish 100 lb ande and 20lb's at strike and had no problems I use 1.3 copper crimps and chafe gear the mono from the crimp to the hook and have put it on the scale usually brakes at about 90lb or so.I just keep a close eye out for chafe and it has been very consitent for us. P.S check your crimps some seem to be a bit larger than others sometimes I can find 1.0 that will fit 100 ande and then I use those.
