Crimping Sleeves – Thimbles – Stop Sleeves
Line Size (Test) Line Diameter Copper Sleeve Size
60 lb. .80mm/0.032″ 1.0mm Mini Double
80 lb. .90mm/0.036″ 1.0mm Mini Double
100 lb. 1.0mm/0.039″ 1.2mm Mini Oval 1.3mm Mini Double
125-130 lb. 1.3mm/0.051″ 1.5mm Mini Oval 1.6mm Mini Double

To be safe you may wish to utilize a thimble so the Mono has a nest to lay in prior to the sleeve 2 B crimped

 

good stuff, thank you

 

You don't need to crimp with the protrolls. I just use a 30lb fluro and it works perfect.

 

I crimp everything down to 20# droppers for salmon, and use Duolocks (or equivalent) to link it all together. Very quick to assemble, and makes switching stuff out on the water very easy. I use double barrel copper crimp sleeves from LeaderTec down to 0.6mm for both mono and fluoro for leaders. Haven't had one fail yet. I'd crimp down to 15# if I could find 0.5mm or even 0.4mm double barrel copper crimp sleeves if I could find them. I also crimp 200# mono bumpers for use in front of all our flashers.

 

I got into the crimping, got all set up with high quality everything. Then i decided to do pull tests. It was horrifying. A perfect crimp doesnt come anywhere close to a halfway decent knot. They broke at half the line rating or worse every time.

I wouldnt bother with it.

 

What fails when you crimp?

I've had knots fail in fluoro just from the heat of friction while tying knots and I've had more fluoro knots fail than I have had crimps fail.

 

Hubbs: More spit on your Fluoro and pull the knots tight slowly. Dunno what knot your using but maybe a change is in order?

Oregon Steel: You could be crushing the line by using too much pressure. Try a little less crimp and make sure your sleeves match the line diameter. I like the oval sleeves because the line squeezes against its self and less prone to damage from over crimping. It takes a bit of practice to get the hang of crimping. Don’t overdo it.

 

For the bumpers in front of the 360 flashers I Build my varios lengths (36 & 24 inch) using old downrigger cable which has been crimped.

 

I do the same thing. Seems to work.

All you need to know about crimps and crimping is available at:
http://leadertec.com/tipsandtechniques/crimp_techniques.html
Been using the info on that site for years, it's good info. I have not had any crimps fail yet and I've used crimps on halibut and tuna gear. Crimps hold with a higher % strength than knots.
I suggest mono, not wire, not even multi-strand SS or coated wire.

I believe the Leadertec website recommends melting the tag end to create a small ball of material that cannot pull through the crimp sleeve.

 

Two questions remain. What sleeve for wire and where does Hubbs find .6mm. The smallest I can find in mini double is .8mm.

 

I get the 0.8mm sleeves from Leadertec, and the 0.7mm and 0.6mm online from CatchAllTackle in Maryland. I'm still looking for 0.5mm and 0.4mm to allow me to crimp down to 10# mono/fluoro.

For the heavy bumpers I use the BillFisher sleeves from Fisherman's Marine.

 

I tried some crimping for ProTrolls. It worked but I didn’t want to buy an expensive crimper, I used pliers. Now I’m back to set ups with 80lb Jinkai mono. Ties knots like 30lb Ultra Green. Strong and stiff enough for ProTroll success.

I learned 25 years ago it was a waste of money not to use the correct crimping tool on leaders. I learned correct crimping techniques from warm water salt water fishing. Crimps done correctly will trump knots every time

 

Why do you run wire bumpers with protrolls?
Personally I never have never considered it hence my curiosity. I run 30lb floro or mono bumpers and they work just fine. It just doesn't seem to be an area subject to heavy stress or wear.

 

FnH13:

Those light bumpers work just fine till you get a tangle. If you’re good at avoiding these, you may not see the benefit. Something else. Stiff leader/bumper components force swivels and bead chains to work better if they get a little dirty to reduce twisting. You still need to use a rudder or notched slider above a 360 to avoid line twists especially with soft braid.

If you have loaner rods rigged for inexperienced fishing guests, you’ll be glad they’re set up for that.

 

FYI, I have been buying my crimping supplies from Leadertec for decades and have always been happy with the quality and prices.
