I wrap when the color is just a tad lighter than what I want to finish with, my cooks are generally done with little regard to the stall, other than for timing. What I mean by that, is that since I am cooking around 280F to 300F, I ignore the stall. I figure on a total 8 hour cook time, and work with that. The wrapping is more about color and keeping a little bit of moist environment around the meat.
me: I don't drink anymore
Yelonutz: me either, but, then again, I don't drink any less
