Campy medium cage RD question

I have a medium cage Chorus 10 speed RD on a bike with a 13-29 casssette and I am changing the cassette to an 11-23. Should I bother changing the RD to a standard cage version or will the medium cage function just as well as the short cage with the smaller cassette? Any advantages or disadvantages to the medium cage? Thanks for any info!

Your medium (or even long cage) rear derailleur will work just fine with the 11-23 cassette. A short cage rd will be slightly lighter, may shift very slightly quicker (it's likely you wouldn't even notice the difference) and will certainly lighten your wallet significantly. The advantage to the medium cage is it will "wrap up" more chain than the short cage and will allow a wider range of gearing.

No reason to change. The shifting really should be the same. IMO, the idea the longer cage RDs shift slower is a myth. The shifting is done between the upper jockey pulley and the cogs. The longer cage can just take up more chain slack. The cage does not have to take up the slack before power can be transmitted.
