Decoction will givd you the full bodied mouthfeel and great malty taste while adding additional color, its very easy, instead of step infusion you pull roughly 1/3 of the grain/water into a pot and raise it to your mash temps then boil for a roughly 10 minutes stirring often and then returning to the main mash, do this to bring the mash to each of the temps needed and for mashout, its pretty easy just takes hours, get on youtube and watch braukaiser's videos on the process, it will give you a little higher effeciency and really contributes to creating a great beer
