You guys are tempting me on the Whiskey.
Hmmm, you need that many shades of longwing? The J.Crew pair (lighter variety) are awesome; skip the whiskey, and, maybe the #8 and get another style. What else do you have?
Then again, you could buy the whiskey and sell the j.crews (whiskey gets darker with age, too, so the shade would be close after a while).
