Yup, its all ive been using. With all the filechanges in patchs lately a dynamic tweak file using "search's" as opposed to a static tweak file using "absolultes" has, with a few exceptions, been the way to go. Just tweak cautiously, lotta nodes are different, while some are identical.
edit:
although, the "old school" way to go about it, may no longer be neccessary
