Help with fitting Double Valve Springs & Collets

The last ones that I checked were no stronger in seat and nose loadings than standard single springs. 
However having two coils of thinner gauge they were able to compress further without coil binding than standard ones, allowing their use with a higher lift cam.

But I'm with you in the idea of staying standard unless there's a good reason to go off piste.
