bad news, my cup came in!
ok, i knew it was kinda dumb to spend the money on the special chrysler "travel tumbler" but i figured what the hell.
first it was on back-order for a couple of months but it finally showed up today. out of all the cups i've used in the crossfire, this is the first one that the crossfire cupholder can't handle. amazing.
seems they designed it to taper down so the bottom is narrower than the top and, although it will sit in the holder in straight and level flight, it comes loose in even a fairly gentle turn.
oh well.
