Ah those bands.
You can warm up, activate, and fatigue decel musculature using bands. But nobody other than a complete novice to resistance band exercise will ever impose enough stress with them to cause the adaptations that correlate with increased strength (and how strength is expressed). The point above about not all weighted ball programs being the same is absolutely the most important point in the thread.
Midlo Dad, the Driveline program referenced in this thread addresses just about every argument you've made. The science is there (that means real data, analysis, and interp) and all of Kyle Boddy's writing on the subject is available free to anyone willing to spend the time running through it.
