Good point McG

Because I spend a lot of time in CGCGCD, I've even put the capo on 9 (for A) although I don't usually go higer than 7 (G). If you have guitar (or other fretted instrument) with good intonation and balanced sound then a capo in any position should be fine. A neck join at 12 can cramp your style so 14 adds flexibility.
