I have switched from left handed to right hand (May 2012) and this clearly changed my swing. So I played a few different balls all winter. I have not had a chance to attend a face to face ball fitting, so I used the online self, ball fitting program on the Titleist web site. It recommended the Titleist NXT Tour ball, so that is what I purchased today. If it is not raining cats and dogs tomorrow (it is today) I will use the NXT ball for a round. I will report back with the results.
