Depends on what kind of a game I'm playing, and whether or not I
need the benefits it gives, namely books and blink dogs. With the
option of book-casting, combined with the waterproof blanket from
the SMC, I really don't need the ID for extra spellbooks. Blink dogs
usually turn up in short order also, so there really isn't a need to
stairhop for that either.
All that is for a 'normal' game. For challenge games like limited turns,
the ID is a great place to pick up hard-to-find books, very quickly. I
also think that all players that have yet to win a game should also
stair hop, even if it's just for a while. The extra items/books/blink dog
corpses can help a lot.
"Whip me!" pleads the adom player. The rng replies... "No."
