Ok, here we go on the techy stuff

First kick-point (of flex-point). This is the point point in the shaft where the degree of bending is greatest and determines the ball's launch angle. A lower flex point creates more loft because the "kick" is nearer the clubhead.

Tip stiffness is very similar and simply describes the behaviour of the tip of the shaft where it meets the hosel. A softer tip with launch the ball higher than a stiffer tip.

In the end it's a bit of a trade-off. A higher flex-point and a higher tip-stiffness will mean more accuracy but less distance (in general).

It's difficult to make a recommendation as there's a combination of so many factors to consider. At the end of the day the best decision making tool is how you hit the darn thing so, if you can, spend some time trying out various combinations.

Hope this helps...a little
