			I used to be a no whistle guy. I had a camp this summer where they specificially told us they wanted a whistle on every sub (the camp was run by the local college assigner, a retired D1 womens official -- when in Rome...). Since then, I've just kept on using it.  
 
I have noticed that using the whistle can work to your advantage in one small, but helpful way. If you can consistently get a whistle on the sub before the table gets a horn on him, it makes you look more on top of stuff.
