RE: string and cable length
Not only does the rigging you mention make the bow fell longer. It is longer, by about 1 1/2".
BAD, BAD shop. It's possible they didn't have the right size rigging and used the closest they had. That's no excuse. If this is the case they should have told you so and with your permission ordered the correct size.
As mentioned, they have risked your safety and the possibilty of damaging the bow. There is no excuse for this. React accordingly.
