I was just wondering what do you pro's use instead of "i" in a loop if you have already used it in a previous loop? I cant seem to find a nicer letter to replace it.

Can i make the "i" only affect the function it is in so i can use it over and over again?

Which is better:
One big loop containing everything
A couple of smaller loops.

I only plan to loop threw about 30 things max at once.
