First, addressing the idea that shorter blades feel and sound better because of concentrated mass is just not accurate. I am a fan of Ping, but that is just not accurate. Of course if you hit a head on it’s center of gravity, no matter how long the blade is, it will feel more solid than if you don’t. Solidness of feel and sound has everything to do with the total mass and dimensional characteristics of the head and the materials and processes used to manufacture the head. The more stable they are, the more solid they are and the more solid they are the better they feel. Longer blade lengths make the mass more stable and thus more solid. Also, sound has a lot more to do with feel than most people think. Important to remember that the sound is influenced by the materials and manufacturing processes for sure, and as I mentioned how stable the head based on it’s mass and dimensional characteristics, but also the the type of ball. In short, don’t judge the feel of a club with hard range balls. Your perception should be based on hitting the club with the ball you play.
We basically do what your asking in all our of our players blade designs. By no means do I believe that our blade lengths are long, but they are dimensionally better and more stable than the ones you mentioned and that is by design. Too many times “blades” that are produced by OEM’s are based on products they are designing for a particular tour player, which is fine, but many tour players for whatever reason like to look at shorter blade lengths. I think even they should consider more stable options because they too don’t hit every shot on the cg of the head, but that’s just my opinion, but based on what we know to be factual about the mass and dimensional characteristics of club heads and how it influences ball flight.
We have several new models in the pipeline, so hopefully either something we have or something we have coming will satisfy what you are looking for.
