Effects of changing shafts on a driver

Substituting a low torque shaft with a higher torque shaft

My favorite driver these days is the Acer XP905 460cc Titanium driver. It allows me to easily move the ball both ways and I use the Blue Crush graphite shaft with stiff flex. I like it as it suits my swing (111 MPH swing speed) and gives me consistent results. It is light weight (62 grams) with a very low torque of 2.9.

I wanted to see what will happen if I switch to a shaft that has a higher torque. I picked the Apollo Ultralight Shadow graphite shaft. It is also very light at 62 grams but it's torque is 5.0. Flex was kept Stiff just like the Blue Crush.


  • At my full swing speed (110 to 111 MPH), the Blue Crush gives me solid consistent results. The Apollo Ultralight could not give me similar consistency and I was getting strong pulls instead.
  • At reduced swing speeds (95 to 100), the Apollo Ultralight gives better results. In fact it started giving me those boring ball flights that you see on tour.
  • Even at the reduced swing speed, the Apollo Ultralight was delivering almost the same distance as the Blue Crush at full speed.


  • If your swing speed is between 90 and 100, a low torque shaft like the Blue Crush will be a detriment to your long shots. A higher torque shaft (4.5 to 5.5) will suit your swing better and deliver consistent results.
  • Of course the ideal thing is to get your swing analyzed by an unbiased pro with a computer analysis system and a range of shafts.
