Tie a snell knot. Then the only thing getting beat up by the weight is the hook eye. ....and it adds a bit of noise(the good kind).

I threw away all my Tungsten weights with inserts about 8 years ago. They WILL fray your line and cause you lots of heartache!
I guarantee you your line is breaking for some other reason than the tungsten weight.

Check the Aaron Martin YouTube tip with the shrink tubing. Heat and stretch. Works pretty good. I won't use tungsten without inserts. AND I HAVE TRIED many different brands and on different lines. (The Strike King are the Worst!) I have found a few that are not too bad but you have to check your line frequently. I just get tired of hearing how Wonderful and Polished all these CHEAP ones are and how much better they are, but it's not always true. I guess there are probably a couple Hundred OTHER Brands that I haven't tried yet though!
(How can RUBBER Shrink Tubing fray your line???? Factory Plastic Inserts maybe will.) Works for me. The old Tru Tungsten was pretty good, but most are cheap made now so that the customers buy them. BUT you often get what you pay for!

I tried the shrink wrap thing it wont go thru my tungsten.

Did you heat it and stretch it? Some tungsten and the smaller ones you have to have the smaller size shrink tubing, but even then some of the smaller than 1/4 oz it still might not fit. Bummer!

You may have a problem with your knots or you are trying to make your line last too long. Modern tungsten really won't fray your line.

Check out wicked weights. 97% tungsten 3% nickel diamond bored without all the pretentious filler metals that a lot of tungsten companies use. Never given me a problem on any of my set ups

I like the 98% tungsten

In 20 years or so of using tungsten i guess i have been epically lucky. I gave never had any issues with or without inserts. I jusy buy weights when I need them. I have not seen one model be better than the other for my fishing.

I now usually buy from same couple of places out of convenience more than anything else.

yes heat with a torch and stretch

That�s been my experience as well.

What size weight are you using that doesn't take heat shrink? I've used this on a ton of different weights and never had any issues. Step down in in size if it won't stretch and pull through. Or stretch it more and use a small steel rod to widen it back out.

Swagger tackle and you are done.

No inserts , check your line more often , One of the things I do all the time is check and re-check my line .
