909D3 and 913D3

Adjustability aside, how does the new 913D3 compare with the 909D3?  I have the 10.5 909D3 with the Aldila VooDoo S-Flex.  I've been happy with the club but I'm curious about what the difference might be.  My driver swing speed is about 103 but I hear people comment from time to time about how much they see the shaft bow in my transition, thinking it's an R-Flex.  Comments like that make me wonder the VooDoo is the right shaft for me since there were no others available to try when I bought the club.  Also, how do the 913F3 models compare with the 909F3?

Thanks!

The response to my question was not especially gratifying so I took my 909D3 to Golf Galaxy and compared that to the 913D2 and D3 models.  Although I prefer the look of the smaller D3 head, I was able to get a better launch angle with the D2.  Also, I was about 8 - 12 yards longer with the 913 vs. my 909.  So, there's a 913D2 10.5 @ A1 with the Diamana Blue shaft in my bag now.  

Happy Holidays!
