To address what the original poster said:
I read through this entire thread and only once did I see anything related to “language” or “vocabulary.” I would suggest that what the OP wants is some new language and ability to incorporate that into his current playing. But, at the same time, he seems unwilling or disinterested (for one reason or another) in really investigating the source of a lot of the vocabulary that would lead him to the improved facility he craves.
You don’t have to be a “jazzer” (lol) to add some harmonic and rhythmic vocabulary to your playing. Some simple concepts, when applied in the right places, can add a ton of color and flavor to your playing, no matter what genre you are enmeshed in.
There are a million method books out there of varying degrees of usefulness. One that I always recommend because it doesn’t deal at all with the whole “chord scale” trend is “Hip Licks for Saxophone” by Gregg Fishman. As the name implies, it’s a lick book, but it’s extremely well assembled, offering a ton of classic, usable language in an easily digestible format. It’s really up to the player to take these little bits of information and incorporate them and find ways to expand on them. (The “Licks” part of the title does the book a disservice, I think. It should be called “Hip Language,” because that is what separates blues guys from gospel guys from jazz guys - different language.)
