PRS SE custom 7 - Any good?

[FilthyWhore]

Intonation, mostly. You need strings big enough to stay tight, but small enough you don't have to crank the action up to keep it off the frets, and in many cases when you fret a note the pitch changes significantly more than it normally would. As reference to the topic at hand, 3 years later you can barely find a 7 string smaller than 26.5"!
