I don't think there is a right note. There are a variety of right notes---depending on what we
want to say, as well as what we are capable of saying.
I look at it like a language. Like speaking or writing. The more words and phrases in our
vocabulary the more possibilities we have for expressing ourselves. A limited vocabulary
is going to limit how well we can communicate. Build up the vocabulary by learning new
word and phrases (licks, sequences) and any of us will have more options for expressing
ourselves musically.
As for the bends in question---that is pretty standard fare for rock guitarists from Gilmour
to Lynch. Bending a 7th up to the Root, or the 4th up to the 5th. Half step bends are great,
too. Especially in minour keys/tonalities. The 2nd bent up to the flatted 3rd.... or the 5th up
to the flatted 6th are half step bends that can add a lot of flavour.
Root up to minour 3rd is fun, too. Step and an half.
