As a rule of thumb, for every 1/4" over length you add 1 swing weight.  I would bet your clubs are in and around the D6 mark.  Different shafts will obviously affect swing weight as well.  KBS is a good example.  The balance point is higher and results…

Hi Nick,

Thanks for your reply.

I've also noticed that the Rombax 6X07 is placed towards the lower left hand corner. i.e. low spin/launch

On the Fujikura main site, they identify this shaft as mid/high lunch and mid spin.

Could you explain…
