Hi, last year I had to replace a saddle on, my custom 24 as it kept on breaking the a string. Now the same thing has started happening with the d string and I'm thinking should I just replace the whole lot with a set of graphtech string saver saddles

one genuine PRS saddle costs about the same as a full set of graphtechs so if I'm going to have to replace all 6 eventually then PRS ones will work out very expensive but is genuine best?

Thoughts please .
