Roman Moser Loops ..... are you using them?
Yes, love em. Never let me down. Sort, strong, easy to fit. Less splashy than the longer, standard braided loops. A little more pricy than ordinary loops, but 5 quid or so for 5 which will last for a season or two... Cheap.
I like the occasional flexibility of swapping a leader or polyleader, hence a preference for a braided loop not a nail knot. It's a bit easier, I guess, and can be swapped out on the riverbank.
I have had fly lines cracking at the hinge point (where the braided loop & sleeve end) - but that was after a good season or two of use, and as such I'd consider it normal wear and tear.
Cheers
