I cant post avideo at this time and probably wouldn't know how to anyway but it is strange that it is only my drives that it occurs with everytime! When it happens with any other club i know its because I am throwing my left shoulder back therefore trying to scoop the ball into the air.
i have been thinking of going for lessons so maybe that is my best option.

Do think it could be my grip/ was watching a programme on tv and my grip is nothing like what the guy was saying it should be!!

I seem to grasping the club in mypalm quite tightly but this guy(jim mcclean) says it should be in the fingers more!!

this game doesa my head in!!!
