Hi Phillip - 

The chart you are referring to is published as a helpful reference guide to determine where shafts fall in the trajectory and spin category .  It is not a perfect representation but provides useful information in determining what shafts are similar and which are on opposite ends of the spectrum.

The shafts you have referred to are all similar in specifications and would produce similar spin and launch numbers everything being equal.

Fubuki 63: 3.7 torque / Mid launch

'ilima 60: 3.5 torque / Mid launch

VC Speeder 6.0: 3.5 torque / Mid launch

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 to me the reason for such a discrepency?

Thanks in advance,
