Anyone carry a left-handed club in their bag?

Apart from the obvious.

One my PPs is left-handed but plays right-handed, as do I.

He came out with a comment the other day that it would be a good idea to carry a left-handed club for those occasions when the ball is virtually unplayable right-handed, e.g. up against a bush or a tree.

I thought it was a great suggestion!

Does anyone do this, and if so, which club? Or is just a waste of a club?
