The 2024 Daiwa Certate and 2024 Shimano Twin Power are rigidity-first spinning reels, but they place metal in different parts of the platform. Certate combines a full-metal aluminum Monocoque body with a low-inertia ZAION AirDrive rotor. Twin Power pairs its HAGANE Body with a metal CoreSolid rotor and Infinity Loop line lay.

The Real Difference: Where Each Reel Carries Rigidity
Certate's aluminum Monocoque body supports a large Tough Digigear while the ZAION rotor is designed for quick starts and stops. Twin Power emphasizes the rotating assembly: its metal rotor resists deformation and carries more rotational inertia once moving. Both approaches target alignment under load, but they create different handle responses.
Certate Feels More Immediate
The representative LT4000-CXH is lighter and uses the AirDrive spool, shaft, bail, and rotor concept. That combination favors frequent cadence changes, slack pickup, and techniques where the angler repeatedly starts, stops, or twitches the lure. Magsealed protection is used at the body and line roller on this standard model.
Twin Power Favors a Settled Retrieve
The 4000XG's metal CoreSolid rotor builds a stable cadence once turning. Infinity Loop moves the spool slowly to form dense line lay, while Infinity Cross, Infinity Drive, and the HAGANE drivetrain support loaded retrieves. It suits anglers who prioritize a connected, steady wind under resistance.

How to Choose
Choose Certate when low starting inertia, lower listed weight, and rapid rotor response matter most. Choose Twin Power when metal-rotor rigidity, dense Infinity Loop line lay, and a steady loaded retrieve fit the technique. The matched high-speed 4000-class models have the same gear ratio and very similar retrieve rates, so construction and feel matter more than speed.
Bottom Line
Neither platform is simply the stronger version of the other. Certate concentrates rigidity in a compact full-metal body and keeps the rotor light; Twin Power extends metal into the rotor and adds slow oscillation. Pick the architecture that matches how the lure is worked, then confirm the exact size because spool capacity and weight relationships change across the range.
