Hip, great to hear from you again! What are the changes, time signature and bpm?
For me, I <b>try</b> not to think in terms of "should I do this or should I do that". When I play something, I either know it's what I want or not. My feeling is that you, the artist, know the same. You just have to allow yourself the freedom to make the music you need to make at that time and stop worrying about "what's right". (Sorry for going off the cheesy end like that
Let me know how it goes though.
