I personally also dislike d20's and prefer 3d6 variants, just seems I can never convince everyone else of their statistical superiority.
THIS!
I noted on some other thread about T10, calling 10 and average roll on a d20 is a fallacy; there is no bell-shaped curve on rolling a d20, just a flat 5% for any given number.
>sigh<
Nice to see someone else bugged by this.
