njstone,
I haven't smoked a flying pig yet. What makes them better than the normal sizes? Are the flavors that more pronounced? Is the strength increased due to the size?
This is kind of a weak answer, but it's simply that all the spices and flavor I love in the #9 are simply more evident in the FP. It's almost "in your face," scratch that, not almost, lol. It's a little flavor bomb make no mistake.
That being said, they are not as sweet (though I haven't had one recently ... hmmm ... this weekend is suddenly looking like more fun!), and one of the things I love about the #9--with age--is how wonderfully sweet they are. Reminds me of the first third of a PAM '26.
