Am I missing something on braid splices?

Pretty sure you answered your own question. Loop to loop with a double wall on the wind on will retain the most strength. The step up you talk about is going from the backing directly to the topshot I assume. I think the 15% or so loss is right when going from lighter braid to heavier mono though I have never tested.

I tried splicing 50lb hollow core to 50lb mono. The breaking strength of the splice was dramatically lower than the original strength of the braid. Down from 58lb to about 45lbs--on multiple tests. Increasing the mono to 80lb made it even worse.

The failure mode was always the same, right at the end of the mono, where it was buried in the braid. The sudden increase in diameter when the braid has to "climb up" over the larger diameter mono results in a stress point that leads to premature failure.

I tried cutting the end of the mono on a long taper, but that seemed to make things only a little bit better.

Am I missing something? Is there a trick to avoid this? Or does eveybody just assume the splice is as strong as is "should be" without testing it?

Until someone has a rational explanation for what I am doing wrong, I have gone back to a pair of loops joined with a catspaw. That has never reduced the strength in any way I can measure, I can do them in the cockpit on the fly, AND change topshots if I need to.

Seems like you came into this with your mind already set and you would need someone to break the mind set. There were two suggestions here neither of which you picked up on. Lone Ono mentioned stepping down your mono one size from your braid. Thats how Ive always been told to do it. I would assume it has something to do with the pressure of the hollowcore on the mono. The other suggestion was to sand down the cut end of the mono so it doesnt chafe through the braid. This Ive never heard but if its was Texasblue does then I would take it to the bank. Its the little things that will make the diff in those few lbs you are so frustrated about.
Texasblue and mdees88 like this.

Yeah, the sand down is just an obsessive twist I do to all serves to make sure there are no sharp edges of the mono touching hollow core. It's a stand alone thing I do regardless of sizes etc.
