Unless you can hear a difference between 192 and 224, then no, it's not worth the effort to re-rip.

You may have mis-understood what he was saying (or, just as likely, I misunderstood.

I don't think he is talking about re-ripping his music; but instead ripping it for the first time.

It would only take 17% more disk space to rip/encode at the higher bitrate -- probably about $15 worth of disk space, depending on what size disk(s) he has.

From that perspective, I would say go ahead and use the higher bitrate, even if you're not sure you can tell the difference. As a side benefit, the higher bitrate will take less time to encode. (Less compression = less work for the encoder.)
