One suggestion that I have when doing a high gravity brew that you plan on aging in secondary for a while is to add some rehidrated dry or liquid yeast to the bottling bucket. I use a high floc yeast like the Nottingham because it forms a tight cake and imparts little flavor to the final product...plus the beer is carbed up in like a week. This is how the big brewery in Chico CA does it so it must have some cred.
