Just answered my own questions.

Here is what I have done.

I created the smallest possible bmp possible and saved it as clear.bmp.

I imported that into my map and it works great.

I simply double click the push pin set I would like to "disappear" select the clear icon (the trouble is you can't see it to click on it but you figure it out) and that set will be cleared from the map.

No code and it's really easy to get that set back by simply setting it to a visible push pin.

Please let me know your thoughts
Thanks,
Josh
