I really like the new Alley-Viper. They fixed the backpack/gun issue and gave him some new neat accessories, but then again I liked the Defense of Cobra Island AV too.
As for Cobra Commander, he's an ok figure. I would have gotten two if they were mail aways (one to open and one to keep boxed, like Doc) but as it is I'll just have the one, Cobra card or no.
