At the beginning of the year I purchased a replacement driver (Nike Covert with the factory Stiff shaft) to replace my ~3 year old Cleveland DST300 driver. On the range and in the simulator, the Nike driver went straighter, and had a lower more penetrating ball flight. However, in actual play the cleveland just played better. The problem is that the ball would go WAY up in the air would go further, but then would just fall straight out of the sky.
I think that alot of this is regarding the amount of backspin produced by the club.
Also, the Nike is much more sensitive. My miss is an out to in swing that causes a slice with the nike, but a high "strong fade" with the Cleveland.
The Cleveland has the stock Mitsubishi White 44g shaft. The Nike has the stock Kuro Kage silver shaft.
Is the shaft or head causing the additional backspin? I don't know that I am ready to make another investment in a new club. My driver isn't holding me back right now, my short game is a larger problem. The purpose of this conversation is mostly just for the sake of conversation.
Since they are calling for possible snow flurries this week, I get to spend the next several months talking about golf instead of playing it :(
