I feel like my threebet pot play is seriously lacking when i call threebets. When I am the threebettor, i feel really good about what i do, when i'm not, I'm not very confident at all.

I'd like to have a discussion here on what people normally do postflop when calling in a threebet pot versus light threebettors? What's your calling range most of the time, which flops do you tend to raise with air? Which do you look to float?
