Well I just got a Titanium pack today, so the worst I can do is give them a go. If the problem still persists, then its got to be the saddles.
Quite strange though as I was only breaking strings every 6 months, and they weren't at shows. If I can avoid the string saddle savers then I will, not only cos of cost but sound too.
Saying that I could just jack it in and start playing a Telecaster haha.
