I'm never dissapointed to see troopers lining the pegs. The fact that you can probably find a stormtrooper, DS Trooper, or Biker Scout at every other store right now says that they've done a great job with assortments this last year. I'd bet more troopers are bought than anything else out of these lines because everyone wants at least one and a lot of us get multiples. I'd also bet that they could cook through any current stock of troopers in no time with an itial clearance markdown - not always the case on more of the character driven figs.
For pegwarmers around the twin cities, plan on seeing pretty much any Wave 4 or any Wave 6 figs outside of the McSnowtroopers.
