Push Slices and hooks

[jones]

Does this mean my shaft is too weak for my swing? I had an 8.5 degree Ping G2 with a stiff shaft (up until I broke it by throwing about a month ago) and at least half my drives would either be a push slice, hook, or the ball would curve way left.

I recently bought a used titleist x stiff shaft, 8.5 degree and it seems to hook much less. It still sails left a bit (much less though) and its not doing the crazy duck hook shots that happened with the Ping.

Since I'm relatively new to the game, I really don't know that much info when it comes to club fitting, etc.
