"The laws of physics prevent equalised feel between different plain steel strings. With the new strings the properties are controlled to ensure that four of the strings (the plain G and the [wound] D, A and low E strings) on a standard electric guitar bend through the same pitch intervals for identical player control changes, whether that be through conventional pitch bends... or through use of a tremolo/vibrato arm.

The new strings mean that chord bends can be achieved that have not been possible before on standard guitars, such as Fender Stratocasters with standard tremolo units or guitars with the Floyd Rose locking tremolo system.

All electric guitar players can benefit from the new strings... as the optimised sensitivity means that the D string is no longer more difficult to bend than its neighbours and the low E string no longer goes more sharp than the rest of the strings when played hard.

Temperature related tuning problems are also reduced.
I have no clue but you guys can discuss.
