Does your ass hurt at the moment and/or are you getting any other problems in that area? If not leave well alone.
Saddles and shorts tend to be something quite personal. What suits one person can literally be a pain in the arse for another. People can make recommendations, for example I find Funkier shorts very comfortable, others may not. I believe there can also be a difference of opinion about Brooks saddles, but not having ridden a leather saddle for many years, I am reluctant to go through the breaking in period of indeterminate length with no guarantee of success at the end of it.
If you think your saddle is the wrong size for your sit bones,
Evans and some LBS have what is slangly called an arseometer. - A pad you sit on and it measures your sit bones. I found that very useful when the standard saddle on my Cannondale began giving me some jip.
