James,
You will no doubt benifit from having correct fitting
clubs...just like you would with correct fitting shoes.
All
clubs can be fitted and it is usually free if you purchase a set. However some manufactures
clubs i.e
Callaway for example have to be done at the factory due to the hosel design, cast
clubs can be done by the pro who is fitting you.
My only advice would be make sure you are reasonably happy with you swing and you are not a raw beginner because you swing speed may change in 6/12 months of lessons and therfore the shaft in your
clubs may need to change.
If you are happy with your tempo (swing speed) etc then fitting is a must.
Hope this helps.
Ian.
