Eric- you're right on all points- excellent analysis! I'll drop the weight, and add in GHRs (if I can rig up some equipment at the gym) and reveverse hypers. Will also make sure I do the stretches you recommend as well (I'll admit I've never been a big stretcher to begin with...). I keep my ankles at shoulder-width, I'll widen up a bit and see if I get a difference in the movement.

Riddick- thanks as well- I'll try what you recommend, as well as picking up a pair of lifting shoes- I've been using an old pair of running shoes which probably isn't the best.
Thanks!!!
