Just thinking about the hyperpro (ie presumably, progressive) springs .......
I suppose its different preloading a progressive spring compared to a linear one as you would effectively be eliminating some of the softer initial spring rate, and thus changing the overall characteristic of the spring.
With linear, the rate remains constant and is unaffected by preload.
I've not had occasion to consider that before but now that I do, it seems logical.

Maybe in an ideal world, you would have a correctly matched progressive spring and need little or no preload at all.

Also (assuming that the progressive springs are correctly matched in the first place) I would imagine that sag should be increased a little.
I suspect that the best way to set them up might be by using fork travel indicators to assess their maximum deflection at full bump under prevailing riding conditions.

Sorry for the slight hijack but you seem to have covered the main subject now.
