GenCon Art - How Many of Each?

Okay, last year I handed out 1 or more printouts to about 27 companies, so I figure I should take about 15 Hermit Crabs just in case it's wildly popular and half of the people want one. The Sock-Stealing Bird was claimed by only 5 people last year and was the most popular piece, so 15 should be more than enough Hermit Crabs. The question is, how many do I take of everything else? I know last year I misjudged the popularity of a lot of things (I ran out of Shark Hobgoblins!), so I'm sure I'll get something wrong this year and want to err on the side of caution to make sure I don't run out of anything again. Right now I'm leaning towards lots of samurai and the set of 4 Quest Cards (8-10 each), with smaller amounts of landscapes and critters (5-6 each). Also taking a few Cthulhu and Pirate Dragons, because I figure some people will get a kick out of those. Any predictions on what will go over well? = )
