    Shaft Gone Bad Video

    I saw this video and thought it was interesting.



    However, what does Kelvin mean by a 'shaft gone bad?'

    That was Chris Horvath, a long-drive player. He had gotten a XX-flex long-drive shaft that had broken off at the tip and put it into another head (the club still measured 49"!!). Turns out the damage extended farther up the shaft than he thought. The ball went all over the place and really caused me to question the conventional wisdom that the head is a "free body" at impact. We know it isn't "free", it's attached to a shaft, and obviously the properties of the shaft matter, just as what the player does to the shaft matters.

    Is it just crazy ball flight or is there a feel to a bad shaft as well?

    My recollection is there was no unusual "feel" that Chris noticed.

    Isn't the first ball hit higher up on the clubface causing vertical gear effect in the head and the shaft thus bending.. later ball being hit further down aligning with the force vector of the CG and thus no vertical GE ??
