I remember you mentioning limes in a Pisco Sour before. I'm not well versed
with this cocktail so I can't argue the point but the recipes I've seen for it
call for lemon juice. I used to have a roommate whose parents were Peruvian
and I thought he also mentioned lemons but it's not like he drank them very
often so maybe he just didn't know.
I previously wrote that it was my understanding that lemon juice was the
default for a XXX Sour but I can appreciate what you're saying here. Of
course I strive to find a compelling balance of flavor in each of my cocktails
and am not interested in just dumping ingredients together by rote. Perhaps
lemon juice is the standard because it's so widely available and is pretty
consistent in flavor and acidity. In a lot of cases I think the old recipes
worked it out for us, lime juice goes much better with tequila than lemon and
hence lime is the fresh ingreident in a Margarita, a slight variation of a
Tequila Sour.

I'd love to try it, I don't think I've ever had passionfruit juice in a pure
form. I wouldn't have guessed that it was all that acidic, but now I'll keep
my eyes open for finding some. Still, that's something that hardly any bar is
going to carry, you'd definitely have the market cornered on Whiskey Passions
if you were in my city.
