HI guys,

I love golf, and i know of one thing that i do wrong or not enough is my back swing goes back probably 70-75% when it should be going 100% roughly horizontal to the ground. I still get about 225yrds with a 3 wood, but i dont use a 1wood so i need more distance. Do i just have to go to the range and slowly get my swing all the way back. Or is lessons the way to fix this?????????? The scary thing is, is that i hit it dead straight right now and im scared to mess with it. WHat do you guys and gals think

Thanks
