Sufix Ice Braid .14 mm 6# knot break 7# 11 oz.
Sufix Ice Braid .20 mm 10# knot break 10# 0 oz.
The line has quite a bit of body and takes up a lot on the spool. I packed all 75 yards on a Shimano 1000 reel with very little backing. With normal mono of same diameter I could get nearly almost double that on the reel spool. Anyway the line is kind of rough. I still use it but I like other lines far more.
I would looking into the new Sufix 832 braid. It actually has some sinking quality to it and is a lot smoother with 8 strands weave compared to the Sufix Ice Braid of 6 and 10 pound at only 4 strands weave.
Stren Microfuse is another great alternative to Fireline.
Powerpro Ice is also another good line to look into.
