heres something real cheap. first if you have a large window at the back of your house, swing your club whilst looking at your reflection, try to copy what you see the pros doing and by pros i mean say tiger or the goose someone who has a pretty much text book thing going on. then and this is a must if people havnt already said this, IM BAD i didnt read all the other posts. video you swing from behind from in front from all angles, not you obviously, get someone to video you i should have said. then watch the evidence back. i garatee some of the thing you see you wont be happy with a some will just scare you. thats what happened to me anyway, i figured i had a great swing, i looked a bit fruity when i saw mine. not good. best of luck.
