Did you look into the folder where strips are kept? Not sure at all but maybe the folder moved in logic 8.
Typically plugin and ch strip are stored: user -> library -> application support -> Logic
as well as: system drive -> library -> application support -> Logic
I guess you could also look at the package contents on the logic 7 install disc and search for the strip settings and copy them into the folder.
Why logic 8, and not Logic 9?
