Taking your own different weighted sticks to the game (etc)

I carry three sticks, light, medium and heavy to a game, and more often than not I change from one to the other during the game. Sometimes it's simply swap a wet handle for a dry one, but often it's if I start light, but feel I'm not "middling it" I'll change for a heavier one. And vice-versa if I'm not making the tackles.

So I'm wondering if anyone does the same, and for what reasons? Broken sticks don't count, but I suppose they get changed like-for-like anyway!
