Orlimar 440 with an Aldila R shaft. Bought it 3 years ago when i was just getting back into golf after many years. At the time, i hit it against Taylors, Callaways, Pings... it just felt the best, sounded the best, and equalled the longest of the others.
Now after about 300 rounds, and an improving golf game, I'm thinking of getting something new. I tried a Taylor R7 425, and hit it much straighter, and was hitting controlled draws and fades, whereas i'm always fighting a slice on the Orlimar (I hit the occasional fade with my 3 and 4 iron, but am basically a straight hitter).
