Pac-Nor suggested a 1:9 twist when I was shopping for a .243 Win barrel. It works fine for everything, so far, but I haven't shot long bullets, except for Barnes 85 gr. TSX and Hornady GMX 80 gr. bullets, which are about long as 100 gr Sierra SPBTs (and shoot very well).
People are like rifles. Some are tried and true, having great eyes, personality, and fun to be with. Others never seem to hit the mark with you. Still others go off half-cocked. Still, it's nice to know most of them.
