I have to disagree with you... Even though what you say is true for some players(the words and sentences)for example Edward VAN HALEN has 20 favorites licks and he links them together to make his solos (Eddie lovers out there, I'm sorry, but it's a fact, I'm a fan too, but his solos are very predictable)

I try to find some new melody everytime I play a solo, making it up on the spot, or picking what the bassist or drummer are playing, to take it somewhere else, then giving it back to them...
