It doesn't seem like it makes sense since TFC 100D stiff is lighter and higher torque unless the static loft on either club is not within specs.  Btw, are they the same length?  The best is to put yourself on a launch monitor to find out the numbers. 

Thanks for the info. The G5 is 1/2" shorter than stock when it came out. I did play a the other day with the D2, and the launch was a little lower than the G5 but roughly the same distance. A few holes I had a little more distance, others a little less. Again, thanks again for the input and I will utilize your advice in the near future.

You'd be suprised how much of a difference .5* would make. Other than that...shafts play a huge role as well. A little more distance and consistency is a good thing!

I did play a full 18 holes with it the other day, and did notice that the launch was a little lower than my G5. I did notice on a few holes added distance over the G5 and a few holes with a little less difference. Overall, the consistency was about the same as my G5. I did demo the 910 with the RIP shaft in it and like the way it feels. Hopefully I can find one to demo for a full round in the future. Thanks for the input.
