LTDx is an older Cobra family documented in the manufacturer’s 2022 catalogue. An attractive used price is worth investigating only after you know whether the set is standard variable length or ONE Length, and whether its build suits you.

Correcting the LTDx technology description
Cobra documents PWR-COR as a steel core bar suspended in a polymer-injected casing, together with a PWRSHELL forged face cup and adjustable toe weighting. Earlier descriptions of a titanium core, tungsten frame and “PWR-S3” forged heads were unsupported and have been removed.
A forged face cup is a component description; it does not mean the entire head is a traditional one-piece forged blade. Manufacturer claims about speed are design claims, not our measured results or a guaranteed gain over your present irons.
Standard and ONE Length are different purchases
| Reference build | What the 2022 catalogue shows |
|---|---|
| Standard LTDx | 7-iron: 26.5° loft and 37.25-inch listed length; club lengths vary through the set. |
| LTDx ONE Length | 7-iron: 26.5° loft and 37.25-inch listed length; the irons share that listed length. |
| Both examples | PW 41.5°; GW 47.5°. Confirm the actual set and any later alterations. |
The catalogue notes that an Arccos grip adds 0.25 inches in custom. Used clubs may have different grips, shaft lengths or altered lofts. Measure the actual set instead of assuming its current build still matches a stock catalogue.
Check the gaps before committing
A club number is not a distance measurement. With these reference lofts, check the transition from PW to your existing wedges and from the longest iron to a hybrid or fairway wood. Do not replace a set solely because one 7-iron travels farther; compare landing flight and useful gaps.
For ONE Length, try more than the 7-iron. Establish whether you can launch the long clubs and control the short clubs with that setup. A shared playing length is the main buying distinction; a promise that it automatically removes swing inconsistency would go beyond what this guide can establish.
A used-set inspection worth doing
- Photograph every sole and confirm which clubs are included.
- Identify standard or ONE Length from the model markings and measured lengths.
- Check shafts for mismatched labels, damage and signs of poorly fitted replacements.
- Inspect faces, grooves, grips and missing or damaged toe-weight screws.
- Add grip work, missing clubs and a loft/lie check to the delivered price.
Ask about returns before buying if you need to verify measurements. A seller’s “regular flex” summary is not enough: the exact shaft model and actual length are more useful. The catalogue’s original stock choices do not guarantee what is fitted to a used set.
Buying route and verdict
LTDx belongs on a value shortlist when the whole set passes those checks and performs usefully in your own fitting. We have removed the earlier invented launch-monitor table, fixed 2026 prices and unrelated add-on recommendations.
