Are you sure you don't just mean to compare regular Rifle to TT Dynamic Gold?
Rifle Tour Flighted shafts are very different than almost any shaft on the market. They are designed so that the kickpoint of the shaft is lowered as the shaft length increases to help hit long irons higher and short irons lower. In actuality they seem to hit pretty high in general, especially compared to DG's.
The numbered fitting system refers to CPM's or frequency. If you bolt down the grip end and pull and release the head and measure the frequency with an oscilloscope, the higher the frequency, the stiffer the shaft. Royal Precision produces Rifle shafts to match by frequency as opposed to by weight (which is how TT does it).
In terms of True Temper shaft flexes, a DG S300 shaft is about the same flex as a 5.5/6.0 Rifle shaft.
Keep in mind though, that comparing True Temper DG to Rifle Flighted is like apples and oranges as it is more comparable to regular Rifle.
I disagree with the notion that Rifle shafts are designed for harder swingers. However, just as with all other shafts you need to get the right flex. The problem is that many people fail to realize that a Rifle 5.0 is stiffer than a DG R flex and that Rifle 6.0 is comparable to a true temper X flex in terms of frequency. The common misconception is that 6.0 is stiff and 5.5 is regular. This misconception has lead a lot of Rifle shaft users to use way too stiff a shaft. I believe that the reason for this misconception is that since Rifle shafts tend to fly the ball a little higher people fail to realize they're using too stiff a flex in Rifles, but their website has a handy chart for determining which flex is right for you based on 6-iron distance. If you hit your 6-iron 165 yards, you are a 5.5.
