easiest way is to rename your wrappers, so they have a unique name.
then, you can safely delete the wrappers that are not used.
then you can debug the in use wrapper(s)
i don't know how many times i've seen sites with 10 or more 'default' wrappers, when only 1 is being used.
good practice is to name all your wrappers the same as your theme name and not share them. then wrappers have a 1 to 1 relationship with their theme.
