I spooled up a reel with new 10lb invizx last week and fished it for probably 6 hours, landing like 30-40 fish. I used the rod for the second time after spooling it yesterday and I casted off a bait and a few yards of line right away.

I looked at the rest of the line and it didn’t look great either so I had to re spool. Is this what I can expect with these smaller diameter fluoros?

I checked my guides and they all looked good. I was fishing only in open water away from any rocks, wood or anything that could have weakened my line that much.

I feel like invizx has a big drop off in abrasion resistance under 12lb test. I haven't had good luck with any of the lighter lines. I tried it in 6lb on a BFS rod and was having a ton of breakoffs and needing to retie constantly. For lighter fluoro I use Daiwa Samurai hidden now and invizx is reserved for 12+ lb. Tatsu has also performed very well in lighter lb test but price sucks.

Either you got a bad spool of line or something is hurting/nicking the line. Tie an overhand knot and try to break it with your hand is how I check line. I fish the same fluoro for years.

Yeah I kind of feel the same way. I used to use sniper solely but I got some of those bad 12lb spools so I stopped. 15lb+ invizx seems bulletproof but ive casted off probably a half dozen baits on new spools of 10lb in the last 2 seasons. I bought some R18 10lb so I’ll see how that goes.

Respool it with 30 yards of some other fluoro and see if still gets nicks. If it does then you're answer is your rod/reel is the cause. If not, then you got a bad spool of Invizx.

I’ve had the exact same issue with <12lb fluoro.

As diameter decreases, the size of a nick/abrasion it takes to cause failure decreases accordingly. This also decreases the ability to see that weak spot forming exponentially.

I’ve switched to braid and copolymer lines for anything 10lb and under, and am a happier person for it.

This goes without saying, FC is not mono and will not withstand repeated backlashes where I am picking out and yanking on loops and big kinks in my line.

That's a break off waiting to happen.

IME ~ The #1 cause of mysterious FC midline breakoff is . . .

Drum roll, please . . .

Slightly loose line on the spool during a cast.

When there is a the smallest of loose loops—and it is close enough to come in contact with the reel frame—

however slight that contact may be.

With the spool spinning at 4 billion RPMs on the cast

That single spot on the line gets beaten on and, more importantly, gets heated up.

Heat is no good for nylon line.

Sometimes it's significant enough that we can hear it and even feel it.

Sometimes it is slight enough that we don't.

If and when this goes on unnoticed, some time later while making another cast, that spot in the line just fails.

My lure goes bye-bye.

I cannot undo a bad loopy line cast; the damage is done.

If it's in the top section, I can pull down to the bad spot, remove it, and keep fishing.

If it's deep—well, new line time.

If I chose to just ignore it - I'm rolling the dice.

My choice.

Finally, over the years there have been countless threads in these forums all explaining this exact situation.

Bassheads blame bad spools and several other 'reasons' that might or might not have contributed to line failure.

IMO, operator error accounts for 95% of it, but few are willing to accept it.

I do, I know it, and I buy bulk spools.

I've had a lot of issues with Invisx at and below 12lbs as my leader line. I've decided I should probably switch it up.

Although, A-Jay does make a great point.

I have just started using Invizx and I don't have any problems it being weak, but it seems like it doesn't last years like other say. It seems it's getting milky/white after a few days of use.

I agree with this ^^

Fifteen + years of InvizX use with everything from 8 lb. - 25 lb. with very few issues - not enough to get me to change. Every so often I come across a bait/rod combo that shows signs of line burning after use, but it’s rare…and obvious, so easy to work around. I often go 2-3 years between respools.

I agree whole-heartedly

I just don't get it why some are so infatuated with floro. It really offers no significant advantages of mono that cannot be handled with a few modifications of one's presentation. Move on to quality mono and have a much better day.

I was very much of this mindset for a long time.

But I experienced a significant emotional event that completely changed my mind about at least one aspect of FC vs Mono. Fishing side by side with a buddy in Mexico we were long lining 10-inch Bull worms on 1 oz. shakeheads in 30-50 ft. The technique was to drop the baits to the bottom and then drift with the wind up one side of a deep hump—go over the top and then drift and drag the baits down the side back into deeper water. Rods, reels, and baits were identical, but I was fishing 20 lb mono, and Big Fish Jeff was fishing 20 lb FC InvisX, I think. We would call out when we hit bottom and when we were off it. I could NOT keep my baits on the bottom on the same drift—regardless of the amount of line I let out. While Jeff's baits got to and stayed on the bottom far more than mine—like, stupidly more. Accordingly, BFJ was HAMMERING 6-9 lb mutant bass one after another. I was doing nothing. Needless to say, I was not a happy camper. Spooled off the high-float mono that night, went to the FC, and instantly started getting bites the next morning. I learned a valuable lesson and have used it to my advantage ever since. I do like and use mono when the conditions call for it—same goes for my FC use. If I never needed to fish and/or keep a bait deep (which is a relative term in every sense), I'd probably never use FC.

But I do, so I do.

I love #12 InvizX and I 100% feel the same way. I like using #12 for shallow cranks, JBs and lighter T and free rigs in moderate cover. During the winter I use #12 for just about everything, but jigs in tight laydowns, which I use #15 Inviz or #10 BG. On paper the #12 isnt much thicker, but to me, it casts better, has less drag in the water, its not as stiff as #15 in cold water. Ive thought about going to #10, but I think 12 is as low as Im going with InvizX.

I use #12 for chatterbaits as long as I can get away with it. Once the grass grows in, I have to be on the ball, checking for abrasion and avoiding taking up slack. If you get an overrun that hangs mid cast, or use too much pressure to pick a loop out, its more than enough to damage #12, and you will pay for it, one way or another. Im going to grab a spool of that Yo Zuri T-7. Ive heard its not as manageable as InvizX, but its got great abrasion resistance.
