Yes that's right, well some folks will get all uppity and correctly say we're talking about compliance, but everyone knows what we mean.
It seems odd because changing to strings with more tension usually means the neck will bend more and raise the strings off the board, and the opposite with lower tension.
If the strings are sitting lower this would indicate the strings have, in fact, a lower overall tension than the Rotosound's, but maybe feel stiffer due to construction.
I'd certainly like it if Cobalts were a fairly high tension.
