Hi there,
If you have already purchased a set of X18 without having them fitted then you are already off on the wrong foot.
Callaways have to be ajusted at the factory due to the hosel design, being 5ft 8' like me you may find they need to be a little flat maybe 2 degrees.
Are the regular/stiff ??????????
On the bright side they are a little heavier than most but this will help you as they are also very long hitting clubs and very forgiving, stck with
Callaway and practice, once you get used to them you may be suprised.
Moving from gravite to steel with a heavy head as well will feel very different.
Let me know about the shaft flex reg/stiff and come back to me.
Ian.
p.s don't go getting the shafts swopped just yet, the pro who sold them you can do that for free.
