lightweight flywheel differences

[TODA AU]

From peoples experiences which lightweight flywheel is better for street use with a HD Exedy Organic clutch? Spoon (4.6kg) or Toda (4.1kg)?
Will the half a kg make any difference in the performance?
I'm decideing between these 2 for my DC2, they are both the same price so thats not a factor.

The SPOON flywheel is a factory style flywheel.
The extra 500g is quite significant when you measure the inertia of the flywheel.
& it's the reduction in inertia that offeres the greatest benifit.

A visual common sense look at the situation shows this quite simply.
Note: The SPOON flywheel is of the same style as the OEM unit.

That is, the flywheel maintains solid material from centre to outer edge.
To reduce the weight, the flywheel becomes thin & can warp if the clutch is ridden heavily.

The TODA unit by comparison is not cast & machined from chromemolly.
Not only is the material strength superior, the design is also superior.

By removing mass from the outer area by use of holes, the inner drive area maintains it's thickness thereby increasing it's strength.
So using the TODA unit, you achieve less inertia, less total weight & higher strength, both through design & material selection.
It is designed specifically for the sports street driver & has no negative side effect.
