Nike has advanced its polymetal grooves concept with the Nike Method Core 1I, by introducing a polymer-aluminum face insert that should lesson unwanted vibrations.
The Nike Method Core 1I produces a smooth role but is not as good looking as the original.
The new materials used in the Nike Method Core 1I range give a firmer feel than the original Method designs. The consistent roll remains, even on off centre strikes. Particularly impressive from long distance.
