1. whistling when reaching a certain speed - thought it was spokes, but tks to some BFrs, determined it was air moving over the open tube under the crown of the fork... fixed w/a piece of tape...

Harmonic resonance noises are much harder to track down and often harder to fix. Have a Ridley frame that at about 20mph sets up a humming sound. Have not been able to find the reason, so as I rarely get to 20mph except downhill I am just going to live with it.
