If you don't do anything dramatic with the plane, you don't need the vectoring. Once you get into spins, flops and inverted harriers, it is absolutely essential to have the vectoring for recovery. A couple of us found it doesn't like to recover or recovers very slowly without the vectoring particularly with smaller engines. Vectoring makes the airplane overly sensitive for high speed flight and a hard pull at speed with it on might hurt the plane. I'd reommend having it on a switch.
