I have been reading up on glide baits and big swim baits and most are using flouro, with some using braid but giving warning to not chuck it hard. Is this because the knot slips on braid? I have lost a few whopper plopper 130s on 30&50lb braid. When I am not catching, I get bored and see how far I can throw lures. Occasionally I will chuck it so hard the brakes kick in mid flight and the lure goes sailing. Is this because the knot is giving? I use a palomar knot, but from now on I think I will use that with a backup improved clinch when using 1oz+. Maybe I should just lay off the PB casting obsession.

Haven't personally experienced this, but I rarely throw braid. 

Losing a $10+ lure absolutely sucks, this is why most people who fish swimbaits or heavy baits recommend co-poly or mono. A lot more give when something goes wrong. Less chance of your bait just flying off.

Ahh I didnt even consider the stretch factor. This is probably the reason and not that braid is more likely to slip.

If you're using a coated braid, scrape a few inches of the  end of the braid between your fingernails to take the coating off so the line can grip itself.

I use Power Pro braid with my Arigs.  I only tie with one knot, (Pitzen).  I don't have line slippage.

I use braid and have not lost one since going to a doubled uni. 

I use a Uni Knot with every line/lure.  I have straightened out jig hooks with 30# and a steady pull.  No line slippage at all.

 

I don't see how a reel's brakes kicking in could cause any kind of a problem.  Them would be some kind of brakes. 

Most SBer's use 20-25 lb. mono or copoly.  I like 20 lb. CXX for this.

It's not about the knot giving so much as the fluoro is being stretch, weakened, and breaking during the casting process. All that braid with no stretch, and then 18" of fluoro to absorb the shock of a 1oz+ lure... I've seen this happen first hand when trying to do the same setup with heavier crankbaits like a DT16/20 and the likes.

It's not so your knots don't slip.  It's because if you get a solid backlash that stops your lure mid cast, a heavy lure can snap your braid.

 

I used to think this was hogwash, till it happened to me.  Yes, a heavy lure can snap 50 lb braid if it is suddenly stopped due to backlash.

Never had a not slip with straight braid but I did loose 3/4 ounce topwater when the braid snapped about 20 feet from the knot but I just think it was bad batch of line. It was 50# power pro. I was able to retrieve my lure with a chatterbait so it could of been worse.

Thanks guys. I think I'll go uni knot from now on. I like the looks of it and I'm fairly good at it from tiring leaders to my finesse setup. Now that I think about it it is a backlash causing the spool to abruptly stop and not the brakes.

Bingo......use the doubled or improved and never loose a big lure again
