I was looking for some new braided line a little while ago and was tired of spending money on power pro or spiderwire. I picked up a cheap box of Omniflex to try out, it was only like $7.
First thing I noticed is that it looks like it's actually braided, instead of twisted and waxed together. It has a different feel to it, it almost feels thicker even though it is still very small diameter.
I have used it for 4 or 5 fishing trips now and I can tell you it has it's good and bad points. First the awesome thing is NO WIND KNOTS! There was no break in period, no loops, nothing for me. It feels very predictable to me too, if that makes any sense. I was able to cast well, I didn't notice a major difference. The downside is it is not as smooth as other braids when you are reeling in, I got used to it after the first trip, but it caught me by surprise at first.
Bottom line is I will gladly trade some smoothness for no more wind knots so I'll buy some more soon.
