Ken, I use large nylon 5 gallon paint strainer bags instead of the little hops sack they give you. I use all the oak in primary, and I follow the 14 instructions. I place the skins in a nice loose bag, and I have a spoon that I keep in the primary which keeps the bag submerged so I don't have to stir (punch down). Others have used sanitized shot glasses to keep the bag submerged as well.
I use a 10+ gallon (46L) primary so the spoon fits once I cut 6" off the end. Again, I use all the oak, stir it in well, take my readings, then add the skins and submerge them.
You are using the new formulation of the EP. The previous versions did not come with skins, but if the skins are going to add anything to an already incredible wine, you are in for a real treat. This wine will taste quite good at even 6 months, but you will be doing yourself a real disservice by drinking it then. It really requires 18 months or more to get good.
