Hey LeeD, agree avoid loading, so true.. However, the neutral stance and even semi open stance using an eastern doesn't seem to require the same intensity to the bend/loading up.. I recorded myself today, and noticed that my forehand is definately a modified eastern, and whilst using neutral/semi open stances there is some level of loading, it seems far less than the SW stance.. The thought behind the old school stance is gettin foreward momentum into the neutral stance, this avoids loading up the back leg, although semi open stance does take a little more loading...
Bottom line, LeeD, there seems no escape from loading which ever grip u go with in tennis, or stance, but certainly SW is the harshest of them..Correct me if I am mistaken here please.
