I agree with you, as I have never had a crimp fail. That is the way I always rig with heavier leader.I personally have never once had a crimp fail. I've had knots fail. But I was taught to use the RIGHT size of double-sleeve crimps, and use the right tool, and crimp with care and carefully check the end result. After watching a lot of fish being caught, and lost, over more than six decades I've learned that being hasty and overconfident with knots and any other part of your connections to a fish is a time-bomb waiting to go off. Usually just outside of gaff reach.
I have read on here from a lot of different posts that guys are tying leader directly to their
madmac or halos with good success.
Even Fish dope Mentioned it.
I guess it must swim better or better hook up ratio?
I’m just trying to optimize my tackle and be prepared as much as possible for what works best.
As you know what they say, failing to prepare is preparing for failure!
