# Low-Deflection Shafts, Explained: What "LD" Actually Does

*Endmass, squirt and carbon — the plain-English guide to the spec every brand markets differently.*

"Low deflection" is the most used — and most misunderstood — spec in cue marketing. Here's what it actually means and whether you need it.

## What Deflection Is

When you hit the cue ball off-center (with english), the shaft flexes and the ball squirts off-line. That squirt is deflection (also called squirt). Less squirt means less aim adjustment on spin shots.

## What Makes a Shaft LD

- **Endmass:** mass near the tip is what moves the cue ball. Less = less squirt.
- **Ferrule:** short or no ferrule reduces endmass (Predator's approach).
- **Construction:** hollow-core maple, laminated shafts, or full carbon all reduce endmass differently.

## The Honest Trade-Off

LD shafts help most on long shots with sidespin. They don't fix fundamentals, and players switching to LD often over-adjust for a week while their brain recalibrates.

## Who Needs It

- **9-ball/10-ball players:** heavy sidespin patterns benefit most.
- **Developing players:** one less variable while learning english.
- **Traditionalists:** if you've played maple for 20 years, a mid-deflection shaft (like Mezz's Hybrid Pro) is the smarter move than full carbon.

## The Lineup

See the [shaft entries in the Cue Database](/cue-database): REVO, Cynergy, Ignite and ZAN are all there with tip diameters and joint specs.
