You guys are really gonna make fun of me but I can't decide between 49 and 50 as my 6th string lol. 49 is more balanced, doesn't bend the neck as asymmetrically, and is slinkier and makes chords ring cleaner. But 50 locks down the 6th string nice and solid. I'm decided on the other gauges. 10,13.5,17,26,36.
