Decoction or step or single

i have only done single infusion mashes. i bought a bohemian pilsenere and the more reading i do i relive i might want to do a decoction or step infusion. i have never done one but i think it looks kinda easy. i need some advice which would you do and why. i would prefer a single infusion, but if decction will make it take better ill do that.

11 lb weyremann pils
1 lb cara foam
1/2 munich type 2

thanks for the help

A single infusion would be fine. A full on decoction mash will add more flavor and darken the color. If I did the decoction I probably would not use the munich. A triple decoction will add similar flavors.
