Whistle in or out during free throws?

[Adam]

My partners this year have had a habit of using the insipid foul tip signal on blocked shots. I couldn't bear to watch what one used when calling a "reach." There are some things we can deviate on (like whether to put your whistle in on the first of two FTs, what brand of shoes to wear, or how you throw the opening tip), but when you start deviating from the norm just because compliance goes against your nature, then we look like tools out there.
