I really like the first section Dave, but if the term "noodling" implies triviality I beg to differ. Haptic means, i.e. those employing physical reflex, seem to me as valid and as capable as any "serious" process in the generation of ideas during improvisation. In any case, whether an end product is profound, happy, or some other quality to a listener depends mostly on the listener's brain and perhaps what he had for breakfast. Sauguet, I read somewhere, when criticised for being superficial and quotidian, replied that there is, after all, such a thing as serious happiness in music, and I agree with him. However, if I attempt to relate it to specifically insouciant means of creation I find myself struggling in pretty deep aesthetic water.
I "seriously" think you might do well to employ "noodling" more often, and in ways of ever increasing complexity and "seriousness".
