One thing S-A has been paying attention to is rail strength. I don't know which version you have, but teh more recent ones have CrMo rails, which are stronger than the steel they previously used. If you contact them with the S/N and model number info of your saddle, you can probably find out if yours can be improved for a reasonable price. Finding a comfortable saddle is such a PITA (sorry!) that I would recommend trying to address the rail issue head on.
