Tell us what’s new in the 2018 ver­sion of the TFi 2135 line?

There are three key tech­nolo­gies in the put­ters, al­though two of them were present in the pre­vi­ous ver­sion. First, you have the TPU insert be­hind the alu­minium Face Cap. That’s there pri­mar­ily for feel. You’ve also got the 2135 sight line, which brings the align­ment guide right up to the ra­dius of the ball. We im­proved that fea­ture last year by chang­ing the fin­ish to make it more vis­ually no­tice­able. But the big change is the new Face Cap. We’ve now got speed op­ti­mised face milling for each in­di­vid­ual head shape in the TFi 2135 line. Even though the pat­terns might look pretty much the same on each head, they’re to­tally dif­fer­ent and unique for each model.

Why does the milling pat­tern change from put­ter to put­ter?

“The put­ters have been de­signed to re­duce the dis­par­ity of roll be­tween pure strikes and off-cen­tre hits. So we low­ered the ball speed on cen­tre strikes and added ball speed on off-cen­tre strikes to pro­duce uni­form dis­tance, no mat­ter where you strike the ball. The ex­act mag­ni­tude of these changes varies based on the shape and weight of the put­ter, so we’ve pro­duced a dif­fer­ent face for ev­ery model within the fam­ily to make sure each one pro­vides per­fect dis­tance con­trol.”
