Thanks for your feedback :D

Obviously, as with many tank builds, the build changes if the enemy team is heavy caster or heavy physical. But I usually don't make any extra builds for that, because most often, you yourself will know what you need most. :)

The idea with regrowth pendant is a good choice too, but the thing is I love doran's items xD

Overall this looks like a decent cho build. However, when you are solo lane, I find its easier to stay in the lane if I buy a regrowth pendant. Some people say that they have mana problems then, but if you are solo lane you really should be spamming your skills because you will just end up pushing. Also if you are fighting a very heavy ad team I'd get a thornmail because cho has a great amount of health. I do like the sunfire and banshee though :)
