Im just using 200lb for west coast stripes both windon and bite leader. 6m windon and 2.8m bite leader. Been working well.

Yep can vouch for kavemans windons very nice

Bob... only available from me at present. $15 each or $50 for 4

The best thing about using JB hollow is how thin it is compared to using dacron. What line weight are you using? pretty sure the Aftco HD are sweet (all my gear on boat at present)

thickest point always the dacron/mono connection, that is one of the advantages of using JB, very thin compared to dacron and also a lot stronger.

 bimimi or loop to loop are very small knots/connections

400lb windons using JB hollow are 3.5mm at widest point(which is the double serve using waxed thread)  300lb are 2.9mm and 200lb are 2.4mm

using dacron, they are 3.8mm for 400lb

Big foot are the best option for using windons but I replaced just the tip  roller with a big foot on one of my rods that had the hd rollers and it works ok with 300lb windon saves the cost of doing all the guides

What length double is best to use before joining the wind on to mainline?

Too short Matt

I have a mate who has caught a few marlin with mainline too swivel with a simple uni not and no double and then standard length leader.

No doubles for me, roll-over knot to swivel and a 4-5m 200-300lb leader. Seems to take the pain ok, used it on the bluefin with lots of drag. The only thing that is a pain is if You need to shorten them after a heavy day on Makos they can get too short quickly.

That gives me more confidence, I have been rigging all my gear down to poppers, stickbaits and now even my snapper gear with braid to hollowcore than trace or clip swivel and I always go to a snap swivel then to trace for my larger gear. This gives me infinite variations to the hook or popper or lure or jig instantly as Im very comfortable to change tools often.
Good to hear that KAVEMAN uses similar connections with the hollowcore.
I have found no failures, excellent casting in all gear, no sticking with rollers. So far all good.
Bar my marlin lure gear all my connections to hooks are knots and they have never looked like failing even on marlin.
Not sure if I have been lucky or just using a formula that is currently working, though waiting for murphies law to test that.
I'm still concerned with large fishing jumping on my trace zone but looking for that failure to test my gear.
Having not hooked anything larger than 137 kg the real test has yet to come. But overall happy with my systems on every other species I have hooked.
So far a 100% success on all species.
I do this to give better feel and action also other than what I have mentioned above.
