I'm playing in Quito. Elevation 9300ft. Has anyone played them at an altitude like that?

Yes- in breckenridge CO- elevation quite high as well. The balls fly higher you go. Not the same as playing at sea level, for certain.

What number are they? 1, 2, 3 or 4?

I use them by the hundreds for tennis coaching. I never paid much attention to the numbers, but I opened 4 today and each had 1 can of each number.

Which is firmer, heavy duty or extra duty? I need these to put on my back and keep me from sleeping on it.

My cattle dog loves tennis balls! We have to buy the extra duty or he cracks them quickly. Hope this helps!
