I can't help myself here because I love this topic.
So, I always thought I preferred softer hitting cues. But after a lot of time at the table and way too much cash, what I figured out was that I like a relatively stiff shaft but quiet hit. I ordered a Samsara new from them around 25 years ago. Holy hell... Any hit even slightly off center make the most god awful (to me) "PING!" or "PLINK!" sound. The cue moved the ball around very nicely and felt great in my hands. But that sound drove me nuts. So I ended up changing the melamine ferrule and Sumo tip to an ivory ferrule with a Moori tip. That made all the difference in the world. It went from "PING!" or "PLINK!" to a noticeable but satisfying "Dink." (That looks ridiculous in words. But I bet most of you know what I'm talking about.) And the taper didn't change so it was still stiff and moved the cue ball around beautifully. That cue is the only thing I've ever regretted selling.
