2720 : Good sound but stiffer than Slinky's

They sound is very good but are definitely on the stiff side, not as much as a Paradigm but more than Slinky's.

Really nice defined tone, bit more output than Slinky's but it requires a bit more tension and feels stiffer for bending overall.

The sound is more towards a D'Addario NYXL but stiffer bending.

As for durability it's hard to say, I always change strings after 2/3 weeks max, but they seems no different than regular Slinkys.

Regarding the price, they are basically twice as much as Slinky's and in my opinion they are not worth twice. I would much rather stick with Slinkys and change them more often rather than buying a premium set of strings.

Tone and playability will definitely benefit more from newer strings rather than with these ones.
