PLEASE TRUST ME -
Anybody who says 'Red Ice' honestly does not know what they are talking about. It is dreadful stuff.
I was always Penn Super Surf, and had a big stock. When I ran out I panicked and bought Red Ice. Honestly, it was just horrible. I have stripped off and throwing. It got into knots straight from the spool, and I had a few birdies and crack-offs, and I can cast pretty damn well.
Even reeling in sometimes, when lead was snapped off, it would come back in in knots!
I am delighted that Sufix Tritanium is basically the same as Penn Super Surf, and it is awesome stuff.
I have multipliers with 15lb (well, 19lb), 25lb and 35lb, and fish smooth and rocks of Yorkshire coast.
I cast 250 yards with TTR and 19lb on grass. Jelly's on 2oz with 19lb on TT lite. And 35lb's into kelp with Excalibur C.
It is absolutely excellent line.
Cannot comment on some others, but Red Ice is APPALLING!!!!
