My putts keep coming up short — what putter do I need?
Short answer:Coming up short is rarely an effort problem. It is almost always an energy-transfer problem — the putter head is decelerating into impact or losing energy to a twist or wobble. The fix is more head stability and a deeper vertical CG. The Killer Golf Artifact platform with a Base 40 + Anchor stack is engineered to do exactly this.
Why:A higher-MOI head with deeper vertical CG transfers more of your stroke energy into the ball and resists the small twists that bleed pace. Players read this as "my stroke felt right but it came up short."
What to do:Add stability mass — pair the Artifact Wing with a Base 40 (deeper CG, smoother roll) and an Anchor for total head mass. Keep the EQ65 at 0° unless you also have a directional miss.
Quick reference
| Pattern | Likely cause | Mass setup |
|---|---|---|
| Short on lag putts (20 ft+) | Deceleration, low MOI | Wing + Base 40 + Anchor |
| Short on slow / wet greens | Insufficient head mass | Wing or Blade + Anchor (max mass) |
| Short only on uphill putts | Energy loss to wobble | Wing + Base 40 (vertical CG depth) |
| Short and offline | Twist + deceleration | Wing + Base 40 + EQ65 at 0° |

Why this happens
Short putts are an energy-transfer story. The ball starts with the velocity the putter face delivers at impact — and a poorly weighted head delivers less than the player thinks. The head twists, decelerates, or absorbs energy in the body of the putter rather than transmitting it to the ball.
There are three usual causes:
- Deceleration through impact — the player slows the head subconsciously, especially under pressure (most common)
- Low MOI head — the head twists on off-center hits and bleeds energy
- Insufficient mass — a head too light for the player's tempo cannot produce repeatable pace
The first one is partly mental. The other two are equipment.
Hitting it harder is not the answer. A more stable head is.
The mechanical answer
Pace control is governed by two physical properties: head mass and rotational MOI. Higher mass produces more momentum at the same swing speed; higher MOI keeps the head square so more of that momentum reaches the ball.
- Head mass: too light → players push the stroke; too heavy → players pull it short. Match to tempo.
- Rotational MOI: a high-MOI head loses less energy on off-center strikes
- Vertical CG depth: a deeper CG produces a smoother roll with less skid, so more ball energy is forward roll instead of bounce
A right-hander missing low needs to increase head stability and vertical CG depth.
Killer Golf specifications for this fix:
- Head: Artifact Wing (higher baseline MOI than the Blade)
- Base 40: Vertical mass module — deepens CG, reduces skid, improves roll
- Anchor 50: 50 g standalone weight — adds total head mass for slow greens
- EQ65: Set at 0° unless a directional miss is also present
- USGA: All configurations conforming
The Wing + Base 40 + Anchor combination is the Killer Golf "lag putt" preset.
How Killer Golf solves this
The traditional answer to "I keep coming up short" is "buy a heavier mallet." That works partially — but it commits the player to one head weight forever. Slow greens in spring, fast greens in summer, the head doesn't change.
The Artifact platform handles the same fix without committing the head. Bases and Anchors stack onto the Wing or Blade in different combinations: light setup for fast greens, heavy setup for slow greens, deepened CG for lag putts. The same head, tuned for what's in front of you that day.
The platform is fitted through the LPGA Equipment Van and a network of partner pro shops, so the diagnosis happens in person — not from guesswork.

Frequently asked
How do I know if I'm decelerating versus my putter being too light?
Both produce the same miss. A SAM PuttLab or similar session shows head speed at impact directly. If head speed is normal but pace is short, the head is too light or low-MOI. If head speed drops at impact, you're decelerating.
Will adding mass change my stroke?
Slightly — heavier heads reward smoother tempos. Most players find a heavier head helps them stop decelerating because the head wants to keep moving.
Is the Wing better than the Blade for lag putts?
Generally yes — the Wing has a higher baseline MOI and rear-biased mass, both of which help on long putts. The Blade is more popular for shorter, feel-driven strokes.
Does the Base 40 actually change roll, or is it marketing?
It changes vertical CG depth, which measurably reduces initial ball skid. On smooth greens the difference is small; on average greens the ball reaches the hole with more forward roll energy, which translates to better pace.
Can I just put lead tape on my current putter?
Lead tape adds mass but doesn't move CG with precision. It's a partial fix. The Artifact Bases and Anchors are designed to add mass at engineered locations.
What total head weight should I aim for?
Most golfers do well between 350 g and 410 g of head mass. The Wing baseline is in that range; Bases and Anchors take it higher. A fitter can dial it in.
