I carry a Ping G400 driver; a G400 17.5 5 wood and the best club in my bag ..... a Ping G400 20.5 7 wood. You will never get the 7 wood out of my bag. Just my adjusting my grip, I have found a club that can be used as a 5 wood all the way down to a 4/5 iron. Get yourself a 7 wood and find out how versatile it is.
All of these comments/tips are great except that many golf courses don't have short game practice areas where you can use regular golf balls and for sure, you can't go out on the golf course and hit to real greens with regular golf balls. I understand all this and still don't have a way to really practice this shot....
