Wondering your guys opinion on low voltage fasteners. My bundles will have 5RG6 3cat5 4 14/2 speaker wires, probably split the runs a little, but what do you guys suggest to fasten to studs where needed?

I used the screw mounting bases with regular wire ties. But this was only in the theater. If I were doing a whole house, I might use the cable clamps.

They also have wire ties with built in mounting heads:
