FWIW, I have found that the Fluke leads that come bundled with NEW high end meters$$ are consistently excellent in all respects
I've seen and used a lot of them, not just the few I've had, but others as well I worked with.
The ones that come with lower priced meters can be ~ok~ to 'so so..meh'
and ocassionally you score unflexible annoying uncooperative Fluke branded vinyl eels
that just will not 'shape up' or behave
I have never purchased Fluke leads separately as I can't be sure they will be the same as what's supplied with their high end meters,
the prices are ludicrous for what they are,
there are competing brands out there with as good quality (and or better) at a more realistic price
my DUTs don't care what brand of leads I poke them with
That said, There's a good blab happening here that's sorta related that may interest you
