yeah i think u should change ur saddles to graphtech
as for me, i changed my gauge from 9s to 10s coz the 1st string usually break in the middle at the spot where i bend... thats usually due to rusting of strings beyond black brown shit...
changed to 10s cuz they don't break as fast as 09s...
it required minimal setup though... just change the sprng tension behind the bridge and adjust the truss rod a lil...
but for ur case, i think changing to 10s will not really solve the problem if u have a rough saddle, so get a set opf graphtechs... they cost bout $40+ to $50
