100 Bullets at one end, Zot at the other.
Not a big fan of Zot, to be honest (though some / many / all might consider that a recommendation)
If you're not allowing for numbers at the start, then ... I just can't take you seriously - what's wrong with you people? Oh, all right - then it would be A+X. And if you want to file that as AplusX, then I'm going to give you such a slap... (though I would allow "A plus X" with spaces, as any right thinking person would, which still puts it at the front)
