Symptoms of the shaft not being fit properly to the golfer may include any or all of the following:
1) When you hit the ball on the center of the clubface, the strike simply doesn't feel that solid;
2) Lower or higher flight/trajectory than you have been used to seeing with other clubs;
3) A feeling that the shafts are too stiff or too flexible for your taste in the club while being hit;
4) The tendency for the ball to hang out to the fade side of the target line along with the feeling the impact is just not that solid. (The ball hanging out to the right, when accompanied by a solid feel at impact, is more of an indication of a swing error, the swingweight/total weight being too heavy, the club being too long, or the face angle of the woodhead being too open for the golfer's needs.)
