yea grafix, im a huge fan of all olympic lifts but especially high pulls.
Do not do them though unless someone shows you proper technique or you see a video of it, i will look for one for you. They are really nothing like an upright row because of the way your body os positioned and various other things, but from far away it could be viewed as that. Basically you start out in a hang clean position, back arched , grip the same as a clean, then you pull up like your going to do a clean (very explosive as stated) you stop when your hands reac hyour pecs though and bring it back down. It sounds easy here but get someone to show you. With olympic lifts, if you do them wrong you will get yourself hurt, usually rotator cuff injury if done improperly
