I have used it the last 8 trips to the surf and really like it.
Using the 30 lb.
Have used it on three rods no problems.
Zero wind knots and I'm casting as far as ever.
I had a rod I had been using that for some reason I was getting lots of wind knots when I used it.
Used the same reel I had been using, the only difference was the Power Pro Super 8 Slick braid, no wind knots.
I hate the other (original) Power Pro braid, this line is totally different.

Here is their spiel:
Super 8 Slick is a super soft 8 carrier braided line. The combination of the 8 carrier diamond braid construction with PowerPro Enhanced Body Technology resulted in a braided line which is ultra round, smooth as silk and slick as a mono line.
PowerPro Enhanced Body Technology compacts the line to avoid wind knots and digging into the spool. These advantages for the fisherman result in a line which is more quiet in casting, has increased casting distance and super smooth handling.

PowerPro Exclusive EBT (Enhanced Body Technology)
Applies special coating closing the gap between yarns which makes the line ultra smooth and avoids windknots and line digging into the spool!

Accurate and silent long-distance casting
