Epic Speed Triple Diamond LS
CaddyIndex™ breakdown — what the agentic research found across each of the six performance dimensions, with cited sources.
You're a low-handicap golfer (0-5 HCP) at 105+ mph driver speed who wants the rarest tour-issue head in the 2021 Callaway lineup — penetrating low / low flight with adjustable rear weight and tour-spec workability.
You're a mid-handicapper wanting more forgiveness (the standard Epic Speed or Epic Max is the right pick), or you swing under 100mph and need higher launch / spin to keep carry distance.
Pros
- Marketed as the longest Triple Diamond head ever from the brand — lower CG than the Epic Speed Triple Diamond or the Max LS, with a proven distance ceiling
- 8,400+ MOI is exceptional for a tour-spec head — the tour-spec footprint without the typical low-MOI penalty
- 12g adjustable rear weight plus OptiFit hosel plus tour-preferred neutral-to-fade shape — meaningful workability for low-handicap shapers
- Played by multiple major champions on the PGA Tour in 2021
Cons
- Four years out of date — exponential recency penalty drops the published score by roughly 9 points versus a 2025-equivalent
- Tour-only availability through tour fitters — much harder to find used than the retail Epic Speed Triple Diamond
- Requires 105+ mph swing speed to keep the low-launch / low-spin profile in the air — wrong fit for moderate swing speeds
By dimension
Forgiveness
Manufacturer specification documents a very high MOI (8,400+) for a tour-inspired driver — the carbon crown saves 13 grams redistributed to increase MOI and lower CG. Reviewer testing of the shared platform notes the face design and titanium construction combine to produce optimal ball speed, forgiveness and spin robustness on both center and off-center strikes. Top of the low-spin-tour range — exceptional MOI for the tour-spec footprint.
Distance
Manufacturer marketing positions the variant as the longest tour-spec head the brand had produced to that point. Launch coverage confirms the low, forward CG combined with the structural frame and face technology produces best-in-class distance for the tour-spec footprint. Lower CG than the sibling tour-spec model and the GI low-spin sibling. Top of the low-spin-tour range.
Workability
Inspired by tour feedback to produce a neutral look at address with a centre of gravity optimised for increased control and workability. Refined shape helps promote a neutral-to-fade shot shape. The higher toe, more face progression and straighter top line is purpose-built for tour shapers. Tour-only availability through tour fitters confirms the player-targeted shaping brief.
Feel
Reviewer testing of the platform describes balls feeling explosive off the face, with the clubhead very stable through the hitting zone and an excellent feel giving an inspiring sense of precision. Variant-specific commentary notes a great deep sound at impact. Slightly above the family's standard model due to tour-spec premium tactile.
Sound
Reviewer testing of the platform describes a staccato ting at impact with restrained and stealthy volume — a muted but firm crack with carbon-titanium tones. Variant-specific commentary notes a great deep sound at impact. Above the family's standard model — the tour-spec head produces a more refined acoustic signature.
Looks at address
Marketing documents the head combining a higher toe, more face progression and a straighter top line for a look and setup at address tour players prefer. Launch coverage describes the tour-preferred shape with the refined visual signature. A major-championship-winning player chose the platform partly because of the at-address profile. Tour-spec premium aesthetic.
