Ive never had any problems with my ht polars and icemaster golds. Ive caught everything on them. Bluegills, crappie, perch, bass, walleye, pike, and a catfish. I leave them on the lightest spin setting possible. Ive caught 6" perch on 4" fatheads before. If crappies dont feel it and drop it, big fish sure wont! Mine are 7 years old and going strong.
