A fairly common comment about the playability of a cue is that the cue seems "dead" or unresponsive. Alternately, some cues are described as "lively." I have always wondered if this difference in responsiveness might be due to the shaft wood. And then I heard somewhere that Jackson Tan, who makes Viattorre cues, tests shaft wood by bouncing it on a hard surface before selecting a piece to turn down into a shaft. The comment about "bouncing" did NOT go on to say whether he picks the wood that bounces most or that bounces least. I would guess that more bounce would be preferred. So my question is, do any of you test shaft wood by bouncing it (end-wise, of course)? And related to that, wouldn't the piece that bounced the highest have the most "life?" Thanks in advance for any responses.
