I definitely find repetition beneficial. I like to sort something out on the pad, then take it to the kit and apply it in a more musical sense once I have the sticking figured and ideas on how to use it.
Well explained. You highlight a central purpose of rudiments that escapes many drummers. What seems routine and repetitious on a pad can be transformed into something immensely musical on a drum set. Rudiments and kit work aren't mutually exclusive. The first can very much heighten the second when applied creatively.
