QoS 642-642 Progress

So, I finished the QoS book by Odom....awesome read!  I need to go through and make some notes for the chapters though...sort of a second "glance through."  I also picked up the nugget monthly streaming subscription; and am a pretty good way through them now.  Good progress, I need some lab reinforcement and I should be good.  Anyone know any good QoS labs (I have the ONT portfolio....).
