You are right a good call and striker will kee well enough to call.....but win?
........the individuals whom get on stage do so under microphones that pick up any error.....they want strikers that run flawlessly and with little effort........ there is no warm up you must run the voice perfectly....one wrong squeak or tonal flaw and your done.....also a striker that will produce tone that will progressively increase in octaves...but will also maintain the yelp at the end.....
