Deck hardware replacement

During the winter refit I would like to upgrade the deck hardware to spinlock cleats and clutches. Has anyone carried out this mod and would you advise moving all the cleats to the aft or to simply replace them in their original positions? We had some drama with the current camlocks for the genoa sheets refusing to unlock, you can imagine the follow on sequence of events!
I shall post some pictures of progress.
