I just bought a bengal 09 from a friend, he rarely used it.

Now i'm using it a lot and seen that the string is being weared off by the idler wheel.
I see that the angle made by the string from the idler wheel to the string separator is too wide and is making the string to enter too diagonal in the wheel and is getting friction to one of he wheel edges.

what should i do?
i'd think about two options:
- change the string sepparator?
- add twists to one of the upper cable sides so the limb twists al little and compensates the angle .. ? ( think this is not a good idea, but still an idea )
