Power Pro vs. Fireline
When braids first started coming out, I spooled my fresh water rods with Fireline and Spiderwire. On those rods I found that Spiderwire was much easier to tie knots in and much softer (wether that makes any difference is another story). On the Fireline, the same knots to connect leader material, would break off with any kind of hard cast.
When I came home from college, and off of Lake Champlain, I started spooling my salt water rods and reels with braid. I already had a dis-taste for Fireline and Power Pro was cheaper and seemed to hold all the standard knots very well.
The problems I found with Power Pro were:
On my 4400ss and 5500ss I got wind knots no matter how I tried casting and retrieving with 10 & 20 lb line. I know that others have had this problem with the SS's and now over rate the rods to use 30 and 50 pound which seems to stop the problem.
With the problems I had with PP I went back to Fireline on some of my gear. Fireline is also the only one that makes a 14 lb line, which is my favorite choice for fluking and weakfish fishing. I learned that the trick for this stuff is to tie variations on the standard knots. Try doubling the line and using one and a half to two times as many wraps.
The Fireline cured the wind knot problem on the SS's so that goes to show that it is not a casting flaw, it is something to do with the design of the spool and the line.
Not until recently have I suffered any of the "mysterious break-offs" that I have heard many complaints about. On the spool of my Tica Caiman that I use in the surf, I have 30 lb Power Pro and I have lost a few lures this season while starting my cast, not a backlash. ON 30 POUND LINE! I have 30 lb Power Pro on my boat rod for casting lures to stripers and this has never happened. Power Pro also SOMETIMES comes with lumps on it if you look.
It seems that the quality control department at Power Pro needs to do a little work. Buying a 300 yard spool of line for $20 to $25 dollars, you should get the quality you expect when you pay for it. For now I am switching back to Fireline, where I know that when a knot fails it was due to me not tying the know correctly and not the line.
I know how to tie a wide variety and variations of knots, very well. I am also quite confident in my casting abilities. So I am sure that my problems with the line are not the fault of myself.
