I have never taken lessons, but I have used many tips from this site as well as many of the pros that I golf with occasionally. In the last 6 years since I have started playing competitively, I have worked myself from a 26 handicap to an 8. It's amazing how many things there are that can cause a slice!
I have corrected my set up for my driver and I now have a absolutely straight drive that gets about 280 to 300 yrds on average. The only thing left is to get the exact distances down with my new
irons. I am getting closer to an exact distance with each club every round and now that I am not scrambling from the rough after each drive I should be down to a six by the end of September.
