wmclarenf1 Posted October 8, 2012 Report Share Posted October 8, 2012 So please indulge me in an old topic. Are all the models - D1, Premia and V-spec (lets's leave out the ST as we know the face is thinner and non-conforming) exactly the same in head material, face thickness, 60 gram booster weight? Or are there any other engineering and technical differences amongst these 3 models apart from the different colored finishes. Going by google translate which can be off I know, it seems to be that all heads are identical with perhaps head weight (not booster weight) with the V-spec being made heavier. And if so, are the D1 and Premia same in head weight and everything else except color finish? And if D1 and Premia are identical, then is is correct to deduce that Premia, according to Ryoma's robot test, gets more distance ONLY due to the longer shaft length of the Premia setup of 46.5 inches as opposed to the 45.25 inches setup of the D1? Annnddd...... :-) if this is the case, then a D1 with the same shaft of the Premia at 46.5 should be as long as the Premia or put the other way, if exactly the same shaft and length was used in the D1 and Premia, would they play exactly the same? Or maybe the Premia is designed to spin more launch higher meaning there are engineering differences? Is the design of the V-spec head meant to make it spin and launch lower than the D1 ad Premia heads? If yes, what is differet in the V-spec that does this? If so, why did Ryoma bother with the D1 and Premia model variation? Just marketing or back to the original question, any engineering differences in the heads. Anyone have the facts? Thanks.

Duffer19 Posted October 8, 2012 Report Share Posted October 8, 2012 The Premia uses a different Ti alloy to the regular D1 according to TSG and also Ryoma's site. I tried the D1, V Spec and own the Premia and all feel different besides the length of shaft. The Premia is the softest in feel. Quote Link to comment Share on other sites More sharing options...

Wonder why Ryoma would bother with a D1 and Premia then. If Premia is as forgiving as the D1 and longer, why would anyone want the D1?

Duffer19 Posted October 8, 2012 Report Share Posted October 8, 2012 If you look at the price point, the D1 is one might consider the entry model with no option for head only. The Premia head alone costs as much as the D1 complete club. Quote Link to comment Share on other sites More sharing options...

+TourSpecGolfer Posted October 8, 2012 Report Share Posted October 8, 2012 Another reason I ask what is different in the Premia over the D1 head. As far as I know it's a different face material that makes it different. Quote Link to comment Share on other sites More sharing options...
wmclarenf1 Posted October 9, 2012 Author Report Share Posted October 9, 2012 As far as I know it's a different face material that makes it different. I'm just trying to understand the technical difference and if that explains the added distance of the Premia over the D1 OR if it is just down to the shaft length with the Premia setup being 1.25 inches longer. Or if it is the face difference, could be it be that the Premia has a thinner BUT still confirming face than the D1 and is more suited for senior golfers who do not pound the ball that hard have more money for the more expensive Premia. Sorry I know I'm getting old on this but I have to be convinced the Premia has technical advantages before deciding to drop more money for one over a D1.
