I'm looking to buy a new driver. I recently payed for a club fitting, and the pro told me I should be playing an extra stiff shaft. I always cut my drivers down to 43 1/2" to 44". My question is does cutting the shaft shorter increase stiffness? In other words if I bought an extra stiff shaft and cut it down am I making it an extra extra stiff shaft? Or would a stiff shaft become extra stiff by cutting it?
