How often do you folks change out your fluorocarbon line? I've found my Berkley "Transition" has turned brittle. I have been treating it with KVD Line Conditioner. This line has only been used since early Spring. I guess I was expecting longer life than that. I'd appreciate comments and suggestions.

in a nut shell, that fluorocarbon has probably some of the worst reviews of any fluorocarbon on the market. there are a lot of issues with break offs, knot failures, etc. i admit i pay the higher price tags for fluoro. some line sits on my reels for months at a time w/o being changed. i have some that is from last fall that is still going great. the occasional spray of line and lure helps. no issues with line failure or breakoffs as long as i check my line. i only change it when i can cast/pitch and the knot hits the line guide. 

I've had some BP XPS fluoro on for over a year now and other than lots of memory, its still good.

Could be your water has a high mineral count. Exposure to sunlight is a bad thing too.

Someone here made the comment the other day by saying we spend 100-300 on a reel, 100-500 on a rod, 3-10 bucks a lure and we buy the cheapest line we can.

I'd jump to no less than Seaguar InvizX or XPS fluoro. Look for the sales. I stock up when I find it.

 I tried some flouro to use as leaders with my braid.  It might have been vanish.  I only remember that I got it at Wal-Mart.  The knot kept breaking.  I lost a couple of lures that way.  Finally put it all on a spinning reel.  It had too much memory and I couldn't get the stuff to straighten out.  It was hard to cast, too, on the spinning reel.  It finally went the way of everything else that doesn't work.

I use both seguar invisex and sunline super sniper. Both of these flouro lines seem to get more supple with use.

I change mine every couple of months but only use about 50 yards at a time, the rest is backing. I've been a big fan of the Seaguar Red Label but recently tried some Sunline Super and have been very impressed with it so far. 

The high end fluorocarbon lines will actually improve with use over time.

The only times you will need to replace line is when a backlash creates

a kink in the line or you simply need more line.

 

If you are spooling with fluoro as you mainline, use backing and no more

than about 60 yarda of fluorocarbon. This will give you 3 spoolings from

a 200 yard package. If you are only using the fluoro as a leader, tie the

connecting knot a few inches above the reel with about 6" or so beyond

the tip.

If you're looking for a good fluoro in the same price range as vanish transition, give seaguar red label a try. It has great knot strength, pretty decent abrasion resistance, and good sensitivity for the money. Definitely worth a try. 

I have three year old InvisX running on two of my drop shot rods.  I treat with KVD L&L after just about every trip.  Line is still strong....strong enough for these guys, anyway:

 

I may have to stock up on some Seguar Flouro. I took 20lb. Viscious floro the last trip down south and it was like a clockspring.

If I don't use my spinners for a while, they will get some coiling.  A little memory isn't such a bad thing with fluoro - better than coils leaping off the spool!  Usually a shot or two of KVD, an hour or so before using them clears that up. Also, it's imperative you troll out the line twist once every 12 hours of use or so.  Storing the line with twist seems to really shorten it's life.
