I like the phrasing of the original question:
Which rye do you taste and say, "if a person tries and likes this, he's hooked for life on rye whiskey, and if he doesn't like it, he really doesn't like rye."
Ritt BIB is my favorite, too, but precisely for its more bourbon-ish and less rye-like qualities -- I don't think it answers the question. WT Rye and JB yellow label (or OO) would be my recommendations (kind of like the Scotch question should split into peated vs. unpeated to really cover all tastes.)
