What tobak do you like for long periods of puffin'

I'm working from home today, sitting in my backyard (CA, so it's always sunny and 70 degrees just like on TV ). It's gonna be a pretty long day of work so I'm expecting to go through a couple bowls. Got the corncob going with the Prince right now, and it will keep me happy for a while (side note, the cob is nice and light, so I can clinch while working away on the laptop).

What do you favor when you expect to be smokin' for a while? Like at a herf, or other situation when it's more than one bowl?
