Question for Ted: Strength or Technique?

[brownman]

I take my b/swing to about 4 " above shoulder height,I feel if I go any higher,I,m out of plane,and the hit isnt as good(hitters pattern),how do I get more length from hitters method.I,ll be honest,on a good day,240-250 metres,I get this feeling that Im just not getting as much out of swing as I can,I just get this feeling that there,s more gas in the tank,how can I acheive more out of swing,Thanks in advance
