I had solid motor mounts in for two years and never had any problems with anything vibrating itself apart, I doubt one solid torque strut would cause any problems. The only time you would notice anything other than a slight buzz would be at start up... the engine jumps quite a bit, but other than that a solid strut is quite managable.
