Why do some prefer a soft tip?
Is it just the feel of the hit or is there another reason?
Good question.
Here's my take on it, a softer hit is less "jarring" therefore it provides a distinctly different "feel" in terms of sensory feedback. The softer hit imparts different "action" on the cueball than if the shot were taken with a harder tip.
For lack of a better word I would say the softer hit is somewhat more forgiving of any stroke deficiencies.
I would tend to think of it as the difference between being hit in the knee cap by ballpeen hammer versus a mallet (of equal weight).
A harder tip has a "crisper" hit, both in relation to sensory feedback, and in the action imparted to the cue ball. Harder tips require more finesse or "touch" but they reward you if your mechanics are rock solid, and you have a decent stroke.
At some point, thru trial and error, thru experience and familiarity most players arrive at a hardness range for their tip that suits them for life.
My advice to you is try some of the different tips, hard, soft, medium, non-laminated and laminated. Eventually you'll find your favorite and that's one less thing to worry about.
BTW--My current choice in Med Hard tips is the Hercules 2.
