Netistä löytyi lopulta valmistajan oma kommentti Diamanojen eroista:

’What is the difference between the Titleist Diamana Blue 65 and Mitsubishi Rayon Diamana Blue Board?

The Titleist Diamana Blue 65 is designed specifically for the Titleist 907 series driver. It weighs 63 grams, features a modestly higher torque value, and shares similar bend profiles with Mitsubishi Rayon Diamana Blue Board. In addition, Titleist Diamana Blue 65 has a longer parallel tip section to accommodate Titleist’s bore-thru hosel design and optimize performance. Players will experience a similar feel and may notice slightly higher launch and spin.’

Tituun on siis saatavilla myös aito Blueboard, mutta silloin on kaivettava lisää kuvetta.
