Diamana Black D-Series vs. 'Ahina for 913D3

Is the Diamana D-Series Black shaft the same as the 'Ahina version for the Titleist 913D3?

Todd,

 The Diamana D+ White will have a similar profile to the Ahina, but will offer more of a firmer butt section, which gives that shaft the firmer feel.  The shaft will still maintain the low launch, low spin profile that the original D series had.
