Aldila NV vs. Titleist Speeder shaft

[TitleistHOG]

I am in the market for a new driver and new fairway metal. I am going to purchase the 905 driver and the 904F fairway metal. What is the difference between these two shafts. I currently have the 983 driver and 980F fairway metal with the Aldila shaft. I was considering purchasing the speeder shaft and wanted to know the difference between the two.

The 905 is a little stiffer at the tip, so try to match the playing characteristics of your current shaft with that in mind. So, go with a slightly softer tipped shaft with otherwise similar characteristics, I'd say.

For the 980 to 904, keep your current shaft. I actually went from an S300 in my 980 to my YS-6F in my 904, and it took awhile to get used to. But having hit a few shots with the YS-6F in the 980, they play nearly identically. The improvements in the 904 are solely in the clubhead with no discernable effect on shaft.
