I play short-scale, I've one 4 and two 5s (With BEADG) and prefer the 5s.
The string spacing is a bit narrow on my GRSM25, but I like it as I can stay in one position (usually about the 5th).
Hopefully soon (in the next year or two! lol) I'll build Phoenix, short scale headless 5er with 18mm bridge string spacing and then I'll be in hog heaven!
