nah... when I found something that never fails me, and I can get 2 reels spooled for less than $12, I quit playing around. If I had a Steez reel, I might would try it, but my guess is it's one of their other brands of line that has just been relabeled to get you to buy it.... very seriously doubt it's worth it.
I have tried the Lake Fork Parahelium, and that has got to be the most limp, softest line - but it was only good for 2 or 3 outings before it started to get the loopty loops in it so I quit using it.
One thing I do with my line (and I buy in bulk), is wrap them in Saran Wrap, put them in a plano watertight box and put them in my basement where it's cool. I've got line that is 2-3 years old that I still haven't used yet and it still comes out brand new. Heat is the biggest destroyer of line. Being in direct sunlight is not good - but it's no where near as damaging as just being in heat.
