I'm not of the thinking that weight contributes at all to feel, aside from the obvious feel of heavy vs. light, or balance. It has been my own experience that most denser woods tend to have a brighter resonance, meaning a more fluid continuity of vibration. Simply put, most denser woods have a bolder feel than less dense woods. Of course there are exceptions, such as koa or lignum. Koa is not dense, but has a strong, albeit dull resonance with fair sustain. Lignum is extremely dense but has a weak resonance with near zero sustain.
Cochen & kamphi rosewoods are among my favorites, and both have extremely bright tone with incredible sustain. A cue made entirely of these woods will be quite heavy, and will feel like you are shattering glass every time you contact the cue ball. Braz rose has a softer pitch but equally long sustain. One of the best playing & feeling cues I ever made was a kamphi forearm with braz handle. The braz base tamed down the kamphi's harsh crispness, but did not impede the flow of vibration. The cue hit hard and bright, but felt like you were pushing the ball with your finger tip. It was amazing. You could feel everything, as if the cue had its own nervous system. If not for an aluminum joint pin & "A" joint screw, the cue would have weighed in the neighborhood of 22oz. Even though the wood was quite high in density, there were no inhibitors of vibration (feel).
